Hans de Goede 2dcc8197fe HID: i2c-hid: Silently fail probe for CHPN0001 touchscreen
The CHPN0001 ACPI device has a _CID of PNP0C50 and even has the _DSM to
get the HID descriptor address, but it is not a HID device at all.

It uses its own protocol which is handled by the (still being upstreamed)
chipone_icn8505 driver. I guess the _CID and the _DSM are the result of
a copy and paste job when the vendor was building the ACPI tables.

Before this patch the i2c_hid_driver's probe function will fail with a
"hid_descr_cmd failed" error.

This commit makes the i2c_hid_driver's probe function instead silently
ignored devices with an ACPI id of CHPN0001.

Log an error in all error paths of i2c_hid_acpi_pdata() instead of having

This is a preparation patch for allowing i2c_hid_acpi_pdata() to fail

Aaron Ma 3e83eda467 HID: i2c-hid: Fix resume issue on Raydium touchscreen device
When Rayd touchscreen resumed from S3, it issues too many errors like:
i2c_hid i2c-RAYD0001:00: i2c_hid_get_input: incomplete report (58/5442)

And all the report data are corrupted, touchscreen is unresponsive.

Fix this by re-sending report description command after resume.
Add device ID as a quirk.

Rodrigo Rivas Costa a955358d54 HID: hidraw: Fix crash on HIDIOCGFEATURE with a destroyed device
Doing `ioctl(HIDIOCGFEATURE)` in a tight loop on a hidraw device
and then disconnecting the device, or unloading the driver, can
cause a NULL pointer dereference.

When a hidraw device is destroyed it sets 0 to `dev->exist`.
Most functions check 'dev->exist' before doing its work, but
`hidraw_get_report()` was missing that check.

Dmitry Torokhov 2e210bbb74 HID: input: fix battery level reporting on BT mice
The commit 581c448476 ("HID: input: map digitizer battery usage")
assumed that devices having input (qas opposed to feature) report for
battery strength would report the data on their own, without the need to
be polled by the kernel; unfortunately it is not so. Many wireless mice
do not send unsolicited reports with battery strength data and have to
be polled explicitly. As a complication, stylus devices on digitizers
are not normally connected to the base and thus can not be polled - the
base can only determine battery strength in the stylus when it is in
proximity.

To solve this issue, we add a special flag that tells the kernel
to avoid polling the device (and expect unsolicited reports) and set it
when report field with physical usage of digitizer stylus (HID_DG_STYLUS).
Unless this flag is set, and we have not seen the unsolicited reports,
the kernel will attempt to poll the device when userspace attempts to
read "capacity" and "state" attributes of power_supply object
corresponding to the devices battery.

Todd Kelner b7289cb1cf HID: sony: Add touchpad support for NSG-MR5U and NSG-MR7U remotes
Sony's NSG-MR5U and NSG-MR7U remote controls have a full keyboard and a
touchpad.  The keyboard is already supported by the existing Linux
kernel and drivers but the touchpad is not recognized.  This patch adds
the coded needed to bring full functionality to the touchpad.

Note that these remotes use the vendor code for SMK even though they are
Sony branded.

Known limitations
- The built-in accelerometers are not supported by these changes
- When the Drag (Fn) key is used as a mouse button, the button is
automatically released when the key begins repeating.  There are two
  workarounds for this 1) Use the button behind the touchpad instead of
  the Drag (Fn) key or 2) Disable the key repeat functionality or
  increase the key repeat delay.

This is the mindless scripted replacement of kernel use of POLL*

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we

Linus Torvalds 168fe32a07 Merge branch 'misc.poll' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs
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"

Hans de Goede edfc3722cf HID: quirks: Fix keyboard + touchpad on Toshiba Click Mini not working
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).

Jason Gerecke 403c0f681c HID: wacom: Fix reporting of touch toggle (WACOM_HID_WD_MUTE_DEVICE) events
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.

Tomasz Kramkowski ac58eec2c5 HID: elecom: rewrite report fixup for EX-G and future mice
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.

Aaron Armstrong Skomra 791ae27373 HID: wacom: EKR: ensure devres groups at higher indexes are released
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).

WARNING: modpost: missing MODULE_LICENSE() in drivers/hid/hid-holtekff.o
see include/linux/module.h for more information

Fix this by moving the module info out of the #ifdef CONFIG_HOLTEK_FF
block and into the un-guarded part of the file.

Jiri Kosina 9abd04af95 HID: elo: clear BTN_LEFT mapping
ELO devices have one Button usage in GenDesk field, which makes hid-input map
it to BTN_LEFT; that confuses userspace, which then considers the device to be
a mouse/touchpad instead of touchscreen.

Fix that by unmapping BTN_LEFT and keeping only BTN_TOUCH in place.

Hans de Goede 127e71bd46 HID: multitouch: Combine all left-button events in a frame
According to the Win8 Precision Touchpad spec, inside the HID_UP_BUTTON
usage-page usage 1 is for a clickpad getting clicked, 2 for an external
left button and 3 for an external right button. Since Linux uses
BTN_LEFT for a clickpad being clicked we end up mapping both usage 1
and 2 to BTN_LEFT and if a single report contains both then we ended
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
HTT5288 i2c mt touchpads.

This commit fixes this by not immediately reporting left button when we
parse the report, but instead storing or-ing together the values and
reporting the result from mt_sync_frame() when we've a complete frame.

Hans de Goede 55746d28d6 HID: multitouch: Only look at non touch fields in first packet of a frame
Devices in "single finger hybrid mode" will send one report per finger,
on some devices only the first report of such a multi-packet frame will
contain a value for BTN_LEFT, in subsequent reports (if multiple fingers
are down) the value is always 0, causing hid-mt to report BTN_LEFT going
1 - 0 - 1 - 0 when pressing a clickpad and putting down a second finger.
This happens for example on USB 0603:0002 mt touchpads.

This commit fixes this by only reporting non touch fields for the first
packet of a (possibly) multi-packet frame.

Hans de Goede af8dc4d094 HID: multitouch: Properly deal with Win8 PTP reports with 0 touches
The Windows Precision Touchpad spec "Figure 4 Button Only Down and Up"
and "Table 9 Report Sequence for Button Only Down and Up" indicate
that the first packet of a (possibly hybrid mode multi-packet) frame
may contain a contact-count of 0 if only a button is pressed and no
fingers are detected.

This means that a value of 0 for contact-count is a valid value and
should be used as expected contact count when it is the first packet
(num_received == 0), as extra check to make sure that this is the first
packet of a buttons only frame, we also check that the timestamp is
different.

Kees Cook e99e88a9d2 treewide: setup_timer() -> timer_setup()
This converts all remaining cases of the old setup_timer() API into using
timer_setup(), where the callback argument is the structure already
holding the struct timer_list. These should have no behavioral changes,
since they just change which pointer is passed into the callback with
the same available pointers after conversion. It handles the following
examples, in addition to some other variations.

Casting from unsigned long:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, ptr);

and forced object casts:

    void my_callback(struct something *ptr)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, (unsigned long)ptr);

become:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

Direct function assignments:

    void my_callback(unsigned long data)
    {
        struct something *ptr = (struct something *)data;
    ...
    }
    ...
    ptr->my_timer.function = my_callback;

have a temporary cast added, along with converting the args:

    void my_callback(struct timer_list *t)
    {
        struct something *ptr = from_timer(ptr, t, my_timer);
    ...
    }
    ...
    ptr->my_timer.function = (TIMER_FUNC_TYPE)my_callback;

And finally, callbacks without a data assignment:

    void my_callback(unsigned long data)
    {
    ...
    }
    ...
    setup_timer(&ptr->my_timer, my_callback, 0);

have their argument renamed to verify they're unused during conversion:

    void my_callback(struct timer_list *unused)
    {
    ...
    }
    ...
    timer_setup(&ptr->my_timer, my_callback, 0);

The conversion is done with the following Coccinelle script:

spatch --very-quiet --all-includes --include-headers \
	-I ./arch/x86/include -I ./arch/x86/include/generated \
	-I ./include -I ./arch/x86/include/uapi \

Eudean Sun 542134c037 HID: cp2112: Fix I2C_BLOCK_DATA transactions
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.

Jason Gerecke 8341720642 HID: wacom: Queue events with missing type/serial data for later processing
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.

Jason Gerecke 99acedadde HID: wacom: Properly handle AES serial number and tool type
Current AES sensors relay tool type and serial number information with
a different set of usages than those prescribed by the modern (i.e.
MobileStudio Pro and newer) EMR tablet standard. To ensure the driver
properly understands these usages, we modify them to be compatible.
The identifying information is split across three consecutive fields:
a 16-bit WACOM_HID_WT_SERIALNUMBER (which is more accurately described
as WACOM_HID_WD_TOOLTYPE), a 32-bit HID_DG_TOOLSERIALNUMBER, and an
8-bit 0xFF000000 (which should be WACOM_HID_WD_SERIALHI). While we're
at it, we also define proper min/max values since may may be undefined
on some devices.

Benjamin Tissoires e04a0442d3 HID: core: remove the absolute need of hid_have_special_driver[]
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.

Note that this change introduces an initial lookup for the device in
hid_gets_squirk(), which should not theoretically be required, but which
actually allows to not have to reparse the list of ignored devices
if we call hid_lookup_quirks twice.

Benjamin Tissoires 6e65d9d549 HID: quirks: move the list of special devices into a quirk
It is better to centralize the information of special devices in one
single file. Instead of manually parsing the list of devices that
have a special driver or those that need to be ignored, introduce
HID_QUIRK_HAVE_SPECIAL_DRIVER and set the correct quirks while fetching
those quirks.

Benjamin Tissoires d5d3e20275 HID: core: move the dynamic quirks handling in core
usbhid has a list of dynamic quirks in addition to a list of static quirks.
There is not much USB specific in that, so move this part of the module
in core so we can have one central place for quirks.
