This series from Benjamin Tissoires finally removes one of the big PITAs
in the hid-core, which is the absolute need of having added all the new
device IDs into the horrid hid_have_special_driver[]
Pull poll annotations from Al Viro:
"This introduces a __bitwise type for POLL### bitmap, and propagates
the annotations through the tree. Most of that stuff is as simple as
'make ->poll() instances return __poll_t and do the same to local
variables used to hold the future return value'.
Some of the obvious brainos found in process are fixed (e.g. POLLIN
misspelled as POLL_IN). At that point the amount of sparse warnings is
low and most of them are for genuine bugs - e.g. ->poll() instance
deciding to return -EINVAL instead of a bitmap. I hadn't touched those
in this series - it's large enough as it is.
Another problem it has caught was eventpoll() ABI mess; select.c and
eventpoll.c assumed that corresponding POLL### and EPOLL### were
equal. That's true for some, but not all of them - EPOLL### are
arch-independent, but POLL### are not.
The last commit in this series separates userland POLL### values from
the (now arch-independent) kernel-side ones, converting between them
in the few places where they are copied to/from userland. AFAICS, this
is the least disruptive fix preserving poll(2) ABI and making epoll()
work on all architectures.
As it is, it's simply broken on sparc - try to give it EPOLLWRNORM and
it will trigger only on what would've triggered EPOLLWRBAND on other
architectures. EPOLLWRBAND and EPOLLRDHUP, OTOH, are never triggered
at all on sparc. With this patch they should work consistently on all
architectures"

The Toshiba Click Mini uses an i2c attached keyboard/touchpad combo
(single i2c_hid device for both) which has a vid:pid of 04F3:0401,
which is also used by a bunch of Elan touchpads which are handled by the
drivers/input/mouse/elan_i2c driver, but that driver deals with pure
touchpads and does not work for a combo device such as the one on the
Toshiba Click Mini.
The combo on the Mini has an ACPI id of ELAN0800, which is not claimed
by the elan_i2c driver, so check for that and if it is found do not ignore
the device. This fixes the keyboard/touchpad combo on the Mini not working
(although with the touchpad in mouse emulation mode).

Touch toggle softkeys send a '1' while pressed and a '0' while released,
requring the kernel to keep track of wether touch should be enabled or
disabled. The code does not handle the state transitions properly,
however. If the key is pressed repeatedly, the following four states
of states are cycled through (assuming touch starts out enabled):
Press: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1
Release: shared->is_touch_on => 0, SW_MUTE_DEVICE => 1
Press: shared->is_touch_on => 1, SW_MUTE_DEVICE => 0
Release: shared->is_touch_on => 1, SW_MUTE_DEVICE => 1
The hardware always properly enables/disables touch when the key is
pressed but applications that listen for SW_MUTE_DEVICE events to provide
feedback about the state will only ever show touch as being enabled while
the key is held, and only every-other time. This sequence occurs because
the fallthrough WACOM_HID_WD_TOUCHONOFF case is always handled, and it
uses the value of the *local* is_touch_on variable as the value to
report to userspace. The local value is equal to the shared value when
the button is pressed, but equal to zero when the button is released.
Reporting the shared value to userspace fixes this problem, but the
fallthrough case needs to update the shared value in an incompatible
way (which is why the local variable was introduced in the first place).
To work around this, we just handle both cases in a single block of code
and update the shared variable as appropriate.

This patch rewrites the mouse report fixup used for the DEFT and HUGE
elecom trackballs in order to make it generic enough to fix other
elecom mice with similar issues. This patch also uses this new report
fixup function to fix the Elecom EX-G trackball which has 6 physical
buttons and a similar issue to the other two mice.
Elecom's track record has so far shown that they like to re-use the
same report descriptor for multiple different mice regardless of the
number of buttons the mouse has. This means that the missing buttons
on multiple mice can be fixed in one function without introducing
phantom buttons which would in turn cause the number of mouse buttons
to be misreported to userspace.
This patch drops the very verbose report descriptor "diff" comment for
a more abridged yet hopefully just as informative generic version.

Background: ExpressKey Remotes communicate their events via usb dongle.
Each dongle can hold up to 5 pairings at one time and one EKR (identified
by its serial number) can unfortunately be paired with its dongle
more than once. The pairing takes place in a round-robin fashion.
Input devices are only created once per EKR, when a new serial number
is seen in the list of pairings. However, if a device is created for
a "higher" paring index and subsequently a second pairing occurs at a
lower pairing index, unpairing the remote with that serial number from
any pairing index will currently cause a driver crash. This occurs
infrequently, as two remotes are necessary to trigger this bug and most
users have only one remote.
As an illustration, to trigger the bug you need to have two remotes,
and pair them in this order:
1. slot 0 -> remote 1 (input device created for remote 1)
2. slot 1 -> remote 1 (duplicate pairing - no device created)
3. slot 2 -> remote 1 (duplicate pairing - no device created)
4. slot 3 -> remote 1 (duplicate pairing - no device created)
5. slot 4 -> remote 2 (input device created for remote 2)
6. slot 0 -> remote 2 (1 destroyed and recreated at slot 1)
7. slot 1 -> remote 2 (1 destroyed and recreated at slot 2)
8. slot 2 -> remote 2 (1 destroyed and recreated at slot 3)
9. slot 3 -> remote 2 (1 destroyed and not recreated)
10. slot 4 -> remote 2 (2 was already in this slot so no changes)
11. slot 0 -> remote 1 (The current code sees remote 2 was paired over in
one of the dongle slots it occupied and attempts
to remove all information about remote 2 [1]. It
calls wacom_remote_destroy_one for remote 2, but
the destroy function assumes the lowest index is
where the remote's input device was created. The
code "cleans up" the other remote 2 pairings
including the one which the input device was based
on, assuming they were were just duplicate
pairings. However, the cleanup doesn't call the
devres release function for the input device that
was created in slot 4).
This issue is fixed by this commit.
[1] Remote 2 should subsequently be re-created on the next packet from the
EKR at the lowest numbered slot that it occupies (here slot 1).

up always reporting the value of both in a single SYN, e.g. :
BTN_LEFT 1, BTN_LEFT 0, SYN. This happens for example with Hantick

The existing driver erroneously treats I2C_BLOCK_DATA and BLOCK_DATA
commands the same.
For I2C_BLOCK_DATA reads, the length of the read is provided in
data->block[0], but the length itself should not be sent to the slave. In
contrast, for BLOCK_DATA reads no length is specified since the length
will be the first byte returned from the slave. When copying data back
to the data buffer, for an I2C_BLOCK_DATA read we have to take care not to
overwrite data->block[0] to avoid overwriting the length. A BLOCK_DATA
read doesn't have this concern since the first byte returned by the device
is the length and belongs in data->block[0].
For I2C_BLOCK_DATA writes, the length is also provided in data->block[0],
but the length itself is not sent to the slave (in contrast to BLOCK_DATA
writes where the length prefixes the data sent to the slave).
This was tested on physical hardware using i2cdump with the i and s flags
to test the behavior of I2C_BLOCK_DATA reads and BLOCK_DATA reads,
respectively. Writes were not tested but the I2C_BLOCK_DATA write change
is pretty simple to verify by inspection.

Userspace expects to receive tool type and serial number information
for the active pen in the very first kernel report, if such data is
supported by the hardware. While this expectation is not an issue for
EMR devices, AES sensors will often send several packets worth of in-
range data before relaying type/serial data to the kernel. Sending this
data "late" can result in proximity-tracking issues by xf86-input-wacom,
or an inability to distinguish different pens by input-wacom.
Options for dealing with this situation include ignoring reports from
the tablet until we get the necessary data, or using the information
from the last-seen pen instead of the (eventual) real data. Neither
option is particularly attractive: the former results in truncated
strokes and the latter causes issues with switching between pens.
This commit instead opts to queue up events with missing information
until we receive a report which contains it. At that point, we can
update the driver's state variables (id[0] and serial[0]) and replay
the queued events.

Most HID devices behave properly when they are used with hid-generic.
Since kernel v4.12, we do not poll for input reports at plug in, so
hid-generic should behave properly with all HID devices.
There has been a long standing list of HID devices that have a special
driver. It used to be just a few, but with time, this list went too big,
and we can not ask users to know which HID special driver will pick up
their device.
We can teach hid-generic to be nice with others. If a device is not
explicitly marked with HID_QUIRK_HAVE_SPECIAL_DRIVER, we can allow
hid-generic to pick up the device as long as no other loaded HID driver
will match the device.
When the special driver appears, hid-generic can step back and let
the special driver handling the device. In case this special driver
is removed, this good old pal of hid-generic will rebind to the device.
This basically makes the list hid_have_special_driver[] useless. It
still allows to not see a hid-generic driver bound and removed during
boot, so we can keep it around.
This will also help other people to have a special HID driver without
the need of recompiling hid-core.

The Wacom Pro Pen 3D includes a third barrel switch which is intended to
be particularly useful in applications where one frequency uses pan, zoom,
and rotate to navigate around a scene or model. The pen is compatible with
the MobileStudio Pro, 2nd-gen Intuos Pro, and Cintiq Pro. When the third
button is pressed, these devices set both the HID_DG_BARRELSWITCH and
HID_DG_BARRELSWITCH2 usages since their HID descriptors do not include a
usage specific to the button.
Rather than send both BTN_STYLUS and BTN_STYLUS2 when the third button is
pressed, userspace (libinput) has requested that we detect this condition
and report a newly-defined BTN_STYLUS3 event instead. We could define a
quirk specific to devices compatible with the Pro Pen 3D, but the liklihood
of seeing both barrel switch bits set with other pens/devices is low enough
to not worry about (pens mechanically prevent accidental activation of
multiple switches).

Several cheap Apollo Lake based laptops / 2-in-1s use an i2c-hid mt
touchpad which is advertised by the DSDT with an ACPI HID of "SYNA3602",
this touchpad can be found on e.g. the Cube Thinker and the EZBook 3 Pro.
On my "T-bao Tbook air" the i2c-hid driver fails to bind to this touchpad:
"i2c_hid i2c-SYNA3602:00: failed to reset device.".
After some debuging this it seems that this touchpad simply never sends
an interrupt after a reset as expected by the i2c hid driver. This commit
adds a quirk for this device, making i2c_hid_command sleep 100ms after
a reset instead of waiting for an irq, fixing i2c-hid failing to bind to
this touchpad.

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.
By default all files without license information are under the default
license of the kernel, which is GPL version 2.
Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.
This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.
How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,
Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.
The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.
The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.
Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if <5
lines).
All documentation files were explicitly excluded.
The following heuristics were used to determine which SPDX license
identifiers to apply.
- when both scanners couldn't find any license traces, file was
considered to have no license information in it, and the top level
COPYING file license applied.
For non */uapi/* files that summary was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 11139
and resulted in the first patch in this series.
If that file was a */uapi/* path one, it was "GPL-2.0 WITH
Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was:
SPDX license identifier # files
---------------------------------------------------|-------
GPL-2.0 WITH Linux-syscall-note 930
and resulted in the second patch in this series.
- if a file had some form of licensing information in it, and was one
of the */uapi/* ones, it was denoted with the Linux-syscall-note if
any GPL family license was found in the file or had no licensing in
it (per prior point). Results summary:
SPDX license identifier # files
---------------------------------------------------|------
GPL-2.0 WITH Linux-syscall-note 270
GPL-2.0+ WITH Linux-syscall-note 169
((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21
((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17
LGPL-2.1+ WITH Linux-syscall-note 15
GPL-1.0+ WITH Linux-syscall-note 14
((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5
LGPL-2.0+ WITH Linux-syscall-note 4
LGPL-2.1 WITH Linux-syscall-note 3
((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3
((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1
and that resulted in the third patch in this series.
- when the two scanners agreed on the detected license(s), that became
the concluded license(s).
- when there was disagreement between the two scanners (one detected a
license but the other didn't, or they both detected different
licenses) a manual inspection of the file occurred.
- In most cases a manual inspection of the information in the file
resulted in a clear resolution of the license that should apply (and
which scanner probably needed to revisit its heuristics).
- When it was not immediately clear, the license identifier was
confirmed with lawyers working with the Linux Foundation.
- If there was any question as to the appropriate license identifier,
the file was flagged for further research and to be revisited later
in time.
In total, over 70 hours of logged manual review was done on the
spreadsheet to determine the SPDX license identifiers to apply to the
source files by Kate, Philippe, Thomas and, in some cases, confirmation
by lawyers working with the Linux Foundation.
Kate also obtained a third independent scan of the 4.13 code base from
FOSSology, and compared selected files where the other two scanners
disagreed against that SPDX file, to see if there was new insights. The
Windriver scanner is based on an older version of FOSSology in part, so
they are related.
Thomas did random spot checks in about 500 files from the spreadsheets
for the uapi headers and agreed with SPDX license identifier in the
files he inspected. For the non-uapi files Thomas did random spot checks
in about 15000 files.
In initial set of patches against 4.14-rc6, 3 files were found to have
copy/paste license identifier errors, and have been fixed to reflect the
correct identifier.
Additionally Philippe spent 10 hours this week doing a detailed manual
inspection and review of the 12,461 patched files from the initial patch
version early this week with:
- a full scancode scan run, collecting the matched texts, detected
license ids and scores
- reviewing anything where there was a license detected (about 500+
files) to ensure that the applied SPDX license was correct
- reviewing anything where there was no detection but the patch license
was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied
SPDX license was correct
This produced a worksheet with 20 files needing minor correction. This
worksheet was then exported into 3 different .csv files for the
different types of files to be modified.
These .csv files were then reviewed by Greg. Thomas wrote a script to
parse the csv files and add the proper SPDX tag to the file, in the
format that the file expected. This script was further refined by Greg
based on the output to detect more types of files automatically and to
distinguish between header and source .c files (which need different
comment types.) Finally Greg ran the script using the .csv files to
generate the patches.

The WACOM_PEN_FIELD macro is used to determine if a given HID field should be
associated with pen input. This field includes several known collection types
that Wacom pen data is contained in, but the WACOM_HID_WD_PEN application
collection type is notably missing. This can result in fields within this
kind of collection being completely ignored by the `wacom_usage_mapping`
function, preventing the later '*_event' functions from being notified about
changes to their value.

The hid descriptor identifies the length and type of subordinate
descriptors for a device. If the received hid descriptor is smaller than
the size of the struct hid_descriptor, it is possible to cause
out-of-bounds.
In addition, if bNumDescriptors of the hid descriptor have an incorrect
value, this can also cause out-of-bounds while approaching hdesc->desc[n].
So check the size of hid descriptor and bNumDescriptors.

In preparation for unconditionally passing the struct timer_list pointer to
all timer callbacks, switch to using the new timer_setup() and from_timer()
(introduced by 686fef928b ("timer: Prepare to change timer callback

This reverts commit 3e70969e44.
This commit causes a few problems for userspace. The most noteworthy are
problems related to the distinguishing of different pens and pointer jumps
when entering proximity. Userspace is written with the expectation that a
pen will provide its tool ID and serial number (if available) in the very
first in-prox report. By sending BTN_TOOL_PEN when the tablet starts
communicating rather than waiting until a tool ID/serial number is
available, userspace ends up treating all pens as being the same and
lacking a serial number. Similarly, userspace assumes that the first
report will contain X/Y data, but by marking the pen as being in-prox
without an X/Y coordinate, userspace ends up warping the pen to the last-
known X/Y location. As of commit 5b40104edf ("HID: wacom: generic: Reset
events back to zero when pen leaves") this means warping to (0,0).

Many devices use a 16-bit timestamp field, with a resolution of 100us,
therefore rolling around very frequently (every 6.5 seconds). To make sure
there is no ambiguity, the timestamp reported to the input stack reset to

The wacom_get_hdev_data function is used to find and return a reference to
the "other half" of a Wacom device (i.e., the touch device associated with
a pen, or vice-versa). To ensure these references are properly accounted
for, the function is supposed to automatically increment the refcount before
returning. This was not done, however, for devices which have pen & touch
on different interfaces of the same USB device. This can lead to a WARNING
("refcount_t: underflow; use-after-free") when removing the module or device
as we call kref_put() more times than kref_get(). Triggering an "actual" use-
after-free would be difficult since both devices will disappear nearly-
simultaneously. To silence this warning and prevent the potential error, we
need to increment the refcount for all cases within wacom_get_hdev_data.

When a pen is first able to to be sensed by the tablet, we would like
to inform userspace that a tool is nearby so that it can attempt to
perform palm rejection. Unfortunately, we don't know any information
about the tool that is nearby, so the best we can do is send a prox
event for a generic BTN_TOOL_PEN. If the pen later comes closer and
enters proximity, we can determine the actual tool type and send
BTN_TOOL_PEN out of prox if necessary.

The legacy Intuos codepath and tablet behavior (e.g. the 1st-gen Intuos
Pro, Cintiq 27, etc.) would result in a BTN_TOOL_* event not being cleared
to zero until the tool had completely left the sensing range of the
tablet. Before the final "out of prox" packet would be sent, zero or
more "in range" packets could be sent to indicate that a pen was still
detectable but not within a useful distance. These "in range" packets
were used by the driver to keep touch input disabled at greater pen
distances. In addition to keeping the `stylus_in_proximity` flag set,
the driver would leave the current BTN_TOOL_* marked as being in
proximity as well.
The new HID codepath also sets `stylus_in_proximity` based on the "sense"
flag, but does not leave the current BTN_TOOL_* marked as being in prox.
This information is potentially useful to for a future userspace-based
palm rejection, so this patch modifies the driver to continue sending it.

The tool ID information sent in ABS_MISC is expected to be reset to 0
when a tool leaves proximity. Not doing this can cause problems if a
tool is removed and then re-introduced. Kernel event filtering will
prevent the (identical) ABS_MISC event from being sent when the tool
re-enters proxmity. This can cause userspace to not properly set the
tool ID.

The latest generation of pro devices (MobileStudio Pro, 2nd-gen Intuos
Pro, Cintiq Pro) send a serial number of '0' whenever the pen is too far
away for reliable communication. Userspace defines that a serial number
of '0' is invalid, so we need to be careful not to actually forward
this value. Additionally, since EMR ISDv4 devices do not support serial
numbers or tool IDs, we'd like to not send these events if they aren't
necessary.
The existing code achieves these goals by adding a check for a non-zero
serial number within the wacom_wac_pen_report function. The MSC_SERIAL
and ABS_MISC events are only sent if the serial number is non-zero. This
code fails, however when the pen for a pro device leaves proximity. When
the pen leaves prox and the tablet sends a serial of 0, wacom_wac_pen_event
dutifully clears the serial number. When wacom_wac_pen_report is called,
it does not send either the MSC_SERIAL of the exiting tool nor an ABS_MISC
event.
This patch prevents the wacom_wac_pen_event function from clearing an
already-set serial number. This ensures that we have the serial number
handy when exiting proximity, but requires us to manually clear it
afterwards to ensure the driver does not send stale data (e.g. when
switching between AES pens that report a serial nubmer of 0 for the
first few fully in-proximity packets).

So it looks like that suspend/resume has actually always been broken on
hid-rmi. The fact it worked was a rather silly coincidence that was
relying on the HID device to already be opened upon resume. This means
that so long as anything was reading the /dev/input/eventX node for for
an RMI device, it would suspend and resume correctly. As well, if
nothing happened to be keeping the HID device away it would shut off,
then the RMI driver would get confused on resume when it stopped
responding and explode.
So, call hid_hw_open() in rmi_post_resume() so we make sure that the
device is alive before we try talking to it.
This fixes RMI device suspend/resume over HID.

"Brazil's Independence Day pull request :-)
This is one of the biggest media pull requests, with 625 patches
affecting almost all parts of media (RC, DVB, V4L2, CEC, docs).
This contains:
- A lot of new drivers:
* DVB frontends: mxl5xx, stv0910, stv6111;
* camera flash: as3645a led driver;
* HDMI receiver: adv748X;
* camera sensor: Omnivision 6650 5M driver (ov6650);
* HDMI CEC: ao-cec meson driver;
* V4L2: Qualcom camss driver;
* Remote controller: gpio-ir-tx, pwm-ir-tx and zx-irdec drivers.
- The DDbridge DVB driver got a massive update, with makes it in sync
with modern hardware from that vendor;
- There's an important milestone on this series: the DVB
documentation was written in 2003, but only started to be updated
in 2007. It also used to contain several gaps from the time it was
kept out of tree, mentioning error codes and device nodes that
never existed upstream. On this series, it received a massive
update: all non-deprecated digital TV APIs are now in sync with the
current implementation;
- Some DVB APIs that aren't used by any upstream driver got removed;
- Other parts of the media documentation algo got updated, fixing
some bugs on its PDF output and making it compatible with Sphinx
version 1.6.
As the number of hacks required to build PDF output reduced, I hope
we'll have less troubles as newer versions of our documentation
toolchain are released (famous last words);
- As usual, lots of driver cleanups and improvements"

The MobileStudio Pro, Cintiq Pro, and 2nd-gen Intuos Pro devices use a
different coordinate system for their touchring and pen twist than prior
devices. Prior devices had zero aligned to the tablet's left and would
increase clockwise. Userspace expects data from the kernel to be in this
old coordinate space, so adjustments are necessary.
While the coordinate system for pen twist is formally defined by the HID
standard, no such definition existed for the touchring at the time these
tablets were introduced. Future tablets are expected to report touchring
data using the same "zero-up clockwise-increasing" coordinate system
defined for twist.

In the reference HID sensor hub firmware all Named array enums were
0-based. There is no description of the default base of enums in HID
sensor hub specification as logical minimum should have set this base
value.
Every sensor hub implemented enum as 1-based, without explicitly setting
logical minimum to 1, because of the implementation by one of the major
OS vendor. In Linux we used logical minimum to decide the enum base.
Some sensor hub FWs already changed logical minimum from 0 to 1. We hoped
that every other vendor will follow. But that didn't happen and we had to
fix the report header for every sensor hub to change logical minimum to 1
by using .report_fixup() callback. So for every new sensor hub we had to
modify source code by adding this quirk based on the vendor and device id.
This is becoming a maintenance burden.
This patch hardcodes the logical minimum of power and report state
attributes to 1. In this way we can remove the existing quirks and also
we don't have to add more quirks.

The WACOM_HID_WD_TOUCHRINGSTATUS usage is a single bit which tells us
whether the touchring is currently in use or not. Because we need to
reset the axis value to 0 when the finger is removed, we call
'wacom_map_usage' to ensure that the required type/code values are
associated with the usage. The 'wacom_map_usage' also sets up the axis
range and resolution, however, which is not desired in this particular
case.
Although xf86-input-wacom doesn't do really do anything with the ring's
range or resolution, the libinput driver (for Wayland environments)
uses these values to provide proper angle indications to userspace.

Put the touchpad in native (absolute coordinate mode) and export it to
userspace as a touchpad rather then as a mouse.
Note this requires HID_QUIRK_MULTI_INPUT as the T100CHI keyboard dock
has all functionality on a single HID interface and userspace expects
touchpads to be on a separate input_dev. Without MULTI_INPUT userspace
will ignore the keyboard part of the keyboard/touchpad combo.

Manufacturers do not always populate serial number in their devices, so
let's fall back to device ID when forming the battery device name. As a
result, batteries in devices without serial number will be named like

(as opposed to hid--battery for the first one, and failing to create

and will get updated once we receive first report containing battery

The 'wacom_update_name' function is responsible for producing names for
the input device nodes based on the hardware device name. Commit f2209d4
added the ability to strip off prefixes like "Wacom Co.,Ltd." where the
prefix was immediately (and redundantly) followed by "Wacom". The
2nd-generation Intuos Pro 2 has such a prefix, but with a small error
(the period and comma are swapped) that prevents the existing code from
matching it. We're loath to extend the number of cases out endlessly and
so instead try to be smarter about name generation.
We observe that the cause of the redundant prefixes is HID combining the
manufacturer and product strings of USB devices together. By using the
original product name (with "Wacom" prefixed, if it does not already
exist in the string) we can bypass the gyrations to find and remove
redundant prefixes. Other devices either don't have a manufacturer string
that needs to be removed (Bluetooth, uhid) or should have their name
generated from scratch (I2C).

Although HID itself is transport-agnostic, occasionally a driver may
want to interact with the low-level transport that a device is connected
through. To do this, we need to know what kind of bus is in use. The
first guess may be to look at the 'bus' field of the 'struct hid_device',
but this field may be emulated in some cases (e.g. uhid).
More ideally, we can check which ll_driver a device is using. This
function introduces a 'hid_is_using_ll_driver' function and makes the
'struct hid_ll_driver' of the four most common transports accessible
through hid.h.

Add support for the Asus T100 touchpad in multi-touch mode (rather
then mouse emulation mode). It turns out that the Asus T100 touchpad
is identical to the already supported i2c-hid Asus touchpads, so
adding support for it was easy.
The only significant difference is that the reported x-coordinates
range on the T100 touchpad is somewhat lower then the range on the
already supported touchpads.
