hammer LED backlight brightness is not getting set when USB
device is in suspend state.
This patch fixes the issue by requesting USB HID device to be
in FULLON mode, so that sending hardware output report and
hardware raw request won't fail to set brightness, and set
device back to NORMAL mode once this call returns.

The Razer Blade Stealth detects palms too aggressively and this creates
a dead zone around the touchpad. Users like being able to use their
entire touchpad, so we should probably not filter out the "palm" events
from the device and report them as regular touches, leaving the palm
detection up to the upper stack

This patch changes all references to ELECOM trackballs using their
series name to refer to them by their model name.
ELECOM provides multiple series of mice such as EX-G, HUGE, and DEFT.
Although it has not caused conflicts in the driver, there can be more
than one iteration of mice in each series. For example, there are 7
variants of EX-G trackballs but only three (M-XT3URBK, M-XT3DRBK, and
M-XT4DRBK) need a driver to work correctly.
There are also 4 DEFT series trackballs but two of them have the same
VID:PID as the other two. I picked the earlier model for the naming of
the PID macros.

Core changes:
- Disallow open drain and open source flags to be set
simultaneously. This doesn't make electrical sense, and would
the hardware actually respond to this setting, the result
would be short circuit.
- ACPI GPIO has a new core infrastructure for handling quirks.
The quirks are there to deal with broken ACPI tables centrally
instead of pushing the work to individual drivers. In the world
of BIOS writers, the ACPI tables are perfect. Until they find a
mistake in it. When such a mistake is found, we can patch it
with a quirk. It should never happen, the problem is that it
happens. So we accomodate for it.
- Several documentation updates.
- Revert the patch setting up initial direction state from
reading the device. This was causing bad things for drivers
that can't read status on all its pins. It is only affecting
debugfs information quality.
- Label descriptors with the device name if no explicit label is
passed in.
- Pave the ground for transitioning SPI and regulators to use
GPIO descriptors by implementing some quirks in the device tree
GPIO parsing code.
New drivers:
- New driver for the Access PCIe IDIO 24 family.
Other:
- Major refactorings and improvements to the GPIO mockup driver
used for test and verification.
- Moved the AXP209 driver over to pin control since it gained a
pin control back-end. These patches will appear (with the same
hashes) in the pin control pull request as well.
- Convert the onewire GPIO driver w1-gpio to use descriptors.
This is merged here since the W1 maintainers send very few
pull requests and he ACKed it.
- Start to clean up driver headers using <linux/gpio.h> to just
use <linux/gpio/driver.h> as appropriate.

Merge tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma
Pull RDMA subsystem updates from Jason Gunthorpe:
"Overall this cycle did not have any major excitement, and did not
require any shared branch with netdev.
Lots of driver updates, particularly of the scale-up and performance
variety. The largest body of core work was Parav's patches fixing and
restructing some of the core code to make way for future RDMA
containerization.
Summary:
- misc small driver fixups to
bnxt_re/hfi1/qib/hns/ocrdma/rdmavt/vmw_pvrdma/nes
- several major feature adds to bnxt_re driver: SRIOV VF RoCE
support, HugePages support, extended hardware stats support, and
SRQ support
- a notable number of fixes to the i40iw driver from debugging scale
up testing
- more work to enable the new hip08 chip in the hns driver
- misc small ULP fixups to srp/srpt//ipoib
- preparation for srp initiator and target to support the RDMA-CM
protocol for connections
- add RDMA-CM support to srp initiator, srp target is still a WIP
- fixes for a couple of places where ipoib could spam the dmesg log
- fix encode/decode of FDR/EDR data rates in the core
- many patches from Parav with ongoing work to clean up
inconsistencies and bugs in RoCE support around the rdma_cm
- mlx5 driver support for the userspace features 'thread domain',
'wallclock timestamps' and 'DV Direct Connected transport'. Support
for the firmware dual port rocee capability
- core support for more than 32 rdma devices in the char dev
allocation
- kernel doc updates from Randy Dunlap
- new netlink uAPI for inspecting RDMA objects similar in spirit to 'ss'
- one minor change to the kobject code acked by Greg KH"

This pull requests contains a consolidation of the generic no-IOMMU code,
a well as the glue code for swiotlb. All the code is based on the x86
implementation with hooks to allow all architectures that aren't cache
coherent to use it. The x86 conversion itself has been deferred because
the x86 maintainers were a little busy in the last months.

This is mostly updates of the usual driver suspects: arcmsr,

hisi_sas. We also have a rework of the libsas hotplug handling to
make it more robust, a slew of 32 bit time conversions and fixes, and
a host of the usual minor updates and style changes. The biggest
potential for regressions is the libsas hotplug changes, but so far
they seem stable under testing.

walk; this is critical to allow forward progress without the need to
use the bioset's BIOSET_NEED_RESCUER.
- Remove DM core's BIOSET_NEED_RESCUER based dm_offload infrastructure.
- DM core cleanups and improvements to make bio-based DM more efficient
(e.g. reduced memory footprint as well leveraging per-bio-data more).
- Introduce new bio-based mode (DM_TYPE_NVME_BIO_BASED) that leverages
the more direct IO submission path in the block layer; this mode is
used by DM multipath and also optimizes targets like DM thin-pool that
stack directly on NVMe data device.

(e.g. scsi_dh) code paths to allow for more optimized support for NVMe
multipath.
- A fix for DM multipath path selectors (service-time and queue-length)
to select paths in a more balanced way; largely academic but doesn't
hurt.
- Numerous DM raid target fixes and improvements.
- Add a new DM "unstriped" target that enables Intel to workaround
firmware limitations in some NVMe drives that are striped internally

Pull xfs updates from Darrick Wong:
"This merge cycle, we're again some substantive changes to XFS.
Metadata verifiers have been restructured to provide more detail about
which part of a metadata structure failed checks, and we've enhanced
the new online fsck feature to cross-reference extent allocation
information with the other metadata structures. With this pull, the
metadata verification part of online fsck is more or less finished,
though the feature is still experimental and still disabled by
default.
We're also preparing to remove the EXPERIMENTAL tag from a couple of
features this cycle. This week we're committing a bunch of space
accounting fixes for reflink and removing the EXPERIMENTAL tag from
reflink; I anticipate that we'll be ready to do the same for the
reverse mapping feature next week. (I don't have any pending fixes for
rmap; however I wish to remove the tags one at a time.)
This giant pile of patches has been run through a full xfstests run
over the weekend and through a quick xfstests run against this
morning's master, with no major failures reported. Let me know if
there's any merge problems -- git merge reported that one of our
patches touched the same function as the i_version series, but it
resolved things cleanly.

- Log faulting code locations when verifiers fail, for improved
diagnosis of corrupt filesystems.
- Implement metadata verifiers for local format inode fork data.

five categories: (1) code cleanups, (2) patches related to adding
PUNCH_HOLE support to GFS2, (3) support for new fields in resource group
headers, (4) a few bug fixes, and (5) support for new fields in journal
log headers. These new fields, which were previously unused, are designed
to make it easier to track down file system corruption, and allow fsck.gfs2
to make more intelligent decisions when finding and fixing file system
corruption.

17. Andreas made a minor cleanup to function gfs2_page_add_databufs.
18. Andreas got rid of function gfs2_log_header_in in preparation for
the new log header fields.
19. Andreas also fixed up some missing newlines in kernel messages.
20. Andy Price added a new field to resource groups to indicate where
the next one should be, to allow fsck.gfs2 to make better repairs.
21. Andy also added new rindex fields for consistency checking.
22. Andy added a crc field to resource group headers for consistency
checking.
23. I added a patch to reduce redundancy in functions common to
freeing dinodes.

between the journalling code and journal recovery code.
25. I added a patch to add new fields to journal log headers based
on a prototype from Steve Whitehouse.
26. I added a patch to log the source of journal log headers so we
can better track down journal corruption.
27. I added a patch to fix a minor comment typo.
28. I also added a patch to fix a BUG in an unlink error path.

Pull GFS2 updates from Bob Peterson:
"We've got 30 patches for this merge window. These generally fall into
five categories:
- code cleanups
- patches related to adding PUNCH_HOLE support to GFS2
- support for new fields in resource group headers
- a few bug fixes
- support for new fields in journal log headers. These new fields,
which were previously unused, are designed to make it easier to
track down file system corruption, and allow fsck.gfs2 to make more
intelligent decisions when finding and fixing file system

Details:
- Two patches from Abhi Das, to trim the ordered writes list, which
used to grow uncontrollably until unmount.
- Several patches from Andreas Gruenbacher: remove an unused
parameter from function gfs2_write_jdata_pagevec, remove a
pointless BUG_ON, clean up an error patch in trunc_start, remove
some unused parameters from truncate, make gfs2_journaled_truncate
more efficient, clean up the support functions for truncate, fix

As Linus points out:
The inode_cmp_iversion{+raw}() functions are pure and utter crap.
Why?
You say that they return 0/negative/positive, but they do so in a
completely broken manner. They return that ternary value as the
sequence number difference in a 's64', which means that if you
actually care about that ternary value, and do the *sane* thing that
the kernel-doc of the function implies is the right thing, you would
do
int cmp = inode_cmp_iversion(inode, old);
if (cmp < 0 ...
and as a result you get code that looks sane, but that doesn't
actually *WORK* right.
Since none of the callers actually care about the ternary value here,
convert the inode_cmp_iversion{+raw} functions to just return a boolean
value (false for matching, true for non-matching).
This matches the existing use of these functions just fine, and makes it
simple to convert them to return a ternary value in the future if we
grow callers that need it.
With this change we can also reimplement inode_cmp_iversion in a simpler
way using inode_peek_iversion.

Pull Wacom device driver updates. These don't have to go on top of the
hid_have_special_driver[] revamp, as the whole group is assumed to
have a special driver based on VID.
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[]
