This is a static checker fix. We write some binary settings to the
sysfs file. One of the settings is the "->startup_profile". There
isn't any checking to make sure it fits into the
pyra->profile_settings[] array in the profile_activated() function.I added a check to pyra_sysfs_write_settings() in both places because
I wasn't positive that the other callers were correct.Cc:

New Genius MousePen i608X devices have a new id 0x501a instead of the
old 0x5011 so add a new #define with "_2" appended and change required
places.The remaining two checkpatch warnings about line length
being over 80 characters are present in the original files too and this
patch was made in the same style (no line break).Just adding a new id and changing the required places should make the
new device work without any issues according to the bug report in the
following url.This patch was made according to and fixes:

Current names are reported as "K750", "M705", and it can be misleading

When a hid driver that uses i2c-hid as transport is unloaded, the hid core
will call i2c_hid_stop() which releases all the buffers associated with the
device. This includes also the command buffer.Now, when the i2c-hid driver itself is unloaded it tries to power down the
device by sending it PWR_SLEEP command. Since the command buffer is already
released we get following crash:[ 79.691459] BUG: unable to handle kernel NULL pointer dereference at (null)

If a touchpad reports the F11 data40 register then this indicates that the touchpad reports
additional ACM (Accidental Contact Mitigation) data after the F11 data in the HID attention
report. These additional bytes shift the position of the F30 button data causing the driver
to incorrectly report button state when this functionality is present. This patch accounts
for the additional data in the report.Fixes:

Pull workqueue update from Tejun Heo:
"Work items which may be involved in memory reclaim path may be
executed by the rescuer under memory pressure. When a rescuer gets
activated, it processes whatever are on the pending list and then goes
back to sleep until the manager kicks it again which involves 100ms
delay.This is problematic for self-requeueing work items or the ones running
on ordered workqueues as there always is only one work item on the
pending list when the rescuer kicks in. The execution of that work
item produces more to execute but the rescuer won't see them until
after the said 100ms has passed, so such workqueues would only execute
one work item every 100ms under prolonged memory pressure, which BTW
may be being prolonged due to the slow execution.Neil wrote up a patch which fixes this issue by keeping the rescuer
working as long as the target workqueue is busy but doesn't have
enough workers"* 'for-3.19' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/wq:

Balance a hid_device_io_start() call with hid_device_io_stop() in the
error path. This avoids processing of HID reports when the probe fails
which possibly leads to invalid memory access in hid_device_probe() as
report_enum->report_id_hash might already be freed via
hid_close_report().hid_set_drvdata() is called before wtp_allocate, be consistent and clear
drvdata too on the error path of wtp_allocate.Signed-off-by: Peter Wu

hidpp_devicenametype_get_device_name() may return a negative value on

The existing generic touch code only reports events after reading an
entire HID report, which practically means that only data about the last
contact in a report will ever be provided to userspace. This patch uses
a trick from hid-multitouch.c to discover what type of field is at the
end of each contact; when such a field is encountered all the stored
contact data will be reported.Signed-off-by: Jason Gerecke

Pull sound updates from Takashi Iwai:
"This became a fairly large pull request. In addition to the usual
driver updates / fixes, there have been a high amount of cleanups in
ASoC area, as well as control API helpers and kernel documentations
fixes touching through the whole tree.In the driver side, the biggest changes are the support for new Intel
SoC found on new x86 machines, and the updates of FireWire dice and
oxfw drivers.Some remarkable items are below:
ALSA core:
- PCM mmap code cleanup, removal of arch-dependent codes
- PCM xrun injection support
- PCM hwptr tracepoint support
- Refactoring of snd_pcm_action(), simplification of PCM locking
- Robustified sequecner auto-load functionality
- New control API helpers and lots of cleanups along with them
- Lots of kerneldoc fixes and cleanupsUSB-audio:
- The mixer resume code was largely rewritten, and the devices with
quirks are resumed properly.
- New hardware support: Focusrite Scarlett, Digidesign Mbox1,
Denon/Marantz DACs, Zoom R16/24FireWire:
- DICE driver updates with better duplex and sync support, including
MIDI support
- New OXFW driver for Oxford Semiconductor FW970/971 chipset,
including the previous LaCie Speakers device. Fullduplex and MIDI
support included as well as DICE driver.HD-audio:
- Refactoring the driver-caps quirk handling in snd-hda-intel
- More consistent control names representing the topology better
- Fixups: HP mute LED with ALC268 codec, Ideapad S210 built-in mic
fix, ASUS Z99He laptop EAPDASoC:
- Conversion of AC'97 drivers to use regmap, bringing us closer to
the removal of the ASoC level I/O code
- Clean up a lot of old drivers that were open coding things that
have subsequently been implemented in the core
- Some DAPM performance improvements
- Removal of the now seldom used CODEC mutex
- Lots of updates for the newer Intel SoC support, including support
for the DSP and some Cherrytrail and Braswell machine drivers
- Support for Samsung boards using rt5631 as the CODEC
- Removal of the obsolete AFEB9260 machine driver
- Driver support for the TI TS3A227E headset driver used in some

Pull devicetree changes from Grant Likely:
"Lots of activity in the devicetree code for v3.18. Most of it is
related to getting all of the overlay support code in place, but there
are other important things in there.Highlights:
- OF_RECONFIG notifiers for SPI, I2C and Platform devices. Those
subsystems can now respond to live changes to the device tree.- CONFIG_OF_OVERLAY method for applying live changes to the device
tree- Removal of the of_allnodes list. This used to be used to iterate
over all the nodes in the device tree, but it is unnecessary
because the same thing can be done by iterating over the list of
child pointers. Getting rid of of_allnodes saves some memory and
avoids the possibility of of_allnodes being sorted differently from
the child lists.- Support for retrieving original DTB blob via sysfs. Needed by
kexec.- More unittests
- Documentation and minor bug fixes"
