If a touchpad does not report relative data then query 6 will not be present and the address
of query 8 will be one less. This patches calculates the location of query 8 instead of
hardcoding the offset.

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.

Before ->start() is called, bufsize size is set to HID_MIN_BUFFER_SIZE,
64 bytes. While processing the IRQ, we were asking to receive up to
wMaxInputLength bytes, which can be bigger than 64 bytes.
Later, when ->start is run, a proper bufsize will be calculated.
Given wMaxInputLength is said to be unreliable in other part of the
code, set to receive only what we can even if it results in truncated
reports.

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.

So here, wacom_open is called, and then wacom_resume is called by the
PM system. However, wacom_open already took the lock when wacom_resume
tries to get it. Freeze.
A little bit of history shows that this already happened in the past
- commit f6cd378372 ("Input: wacom - fix runtime PM related deadlock"),
and the solution was to call first the PM function before taking the lock.
The lock was introduced in commit commit e722409445 ("Input: wacom -
implement suspend and autosuspend") when the autosuspend feature has
been added. Given that usbhid already takes care of this very same
locking between suspend/resume, I think we can simply kill the lock
in open/close.
The lock is now used also with LEDs, so we can not remove it completely.

There is race condition if an interrupt arrives immediately after

and then i2c_hid_get_raw_report() proceed using wrong data.

Provide the resolution of several angular axes (tilt, pen rotation, puck
rotation) to userspace. Because these values are natively degree-based, we
need to convert them to into units/radian as required by the input_absinfo
struct. To ensure wraparound behaves properly for the rotation axes, the
converted value was rounded up rather than rounded nearest.
Notably, the touchring axes (ABS_WHEEL and ABS_THROTTLE) are left without a
a declared resolution because the their low resolution cannot be accurately
represented (the worst-case rounding-induced error would be ~16 degrees).
Pre-scaling the values and range by at least 10x would reduce the error in
the resolution to acceptable levels, but the xf86-input-wacom driver is not
able to use pre-scaled values for these axes at this time.

Pull crypto fixes from Herbert Xu:
- stack corruption fix for pseries hwrng driver
- add missing DMA unmap in caam crypto driver
- fix NUMA crash in qat crypto driver
- fix buggy mapping of zero-length associated data in qat crypto driver
* git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6:
hwrng: pseries - port to new read API and fix stack corruption
crypto: caam - fix missing dma unmap on error path
crypto: qat - Enforce valid numa configuration
crypto: qat - Prevent dma mapping zero length assoc data
in the kernel. The splice logic wants a full page from the ring buffer
but the ring_buffer_wait() returns when there's any data in the ring buffer.
The splice code would then continue the loop waiting for a full page.
But if a full page never happens, the splice code will never sleep and
just continue to loop.
There's another case that Rabin fixed that could loop if there's no memory
and kmalloc() constantly returns NULL.

"Rabin Vincent found a way that tracing could cause an infinite loop in
the kernel. The splice logic wants a full page from the ring buffer
but the ring_buffer_wait() returns when there's any data in the ring
buffer. The splice code would then continue the loop waiting for a
full page. But if a full page never happens, the splice code will

Pull thermal driver fixes from Eduardo Valentin:
"This week we have few fixes:
- fix in IMX thermal driver to do the correct loading sequence with
CPUfreq
- fix in Exynos related to TMU_CONTROL offset in Exynos5260
- fix the unit conversion in int3403"
[ Still pulling from Eduardo as Rui Zhang is on a business trip and has
troubles with his machine ]
* 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal:
imx: thermal: imx_get_temp might be called before sensor clock is prepared
thermal: exynos: use correct offset for TMU_CONTROL register on Exynos5260
thermal: imx: correct driver load sequence for cpu cooling
Thermal/int3403: Fix thermal hysteresis unit conversion
Convert WARN_ONCE() to printk() in selinux_nlmsg_perm().
After conversion from audit_log() in commit e173fb26, WARN_ONCE() was
deemed too alarmist, so switch it to printk().
Signed-off-by: Richard Guy Briggs <rgb@redhat.com>
[PM: Changed to printk(WARNING) so we catch all of the different
invalid netlink messages. In Richard's defense, he brought this
point up earlier, but I didn't understand his point at the time.]

Pull drm fixes from Dave Airlie:
"Radeon and i915 fixes.
I probably should have sent these earlier, but nothing too urgent in
them:
- i915:
blackscreen and corruption fixes
- radeon:
oops, locking and stability"
* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
drm/radeon: add missing crtc unlock when setting up the MC
drm/radeon: use gart for DMA IB tests
drm/radeon: make sure mode init is complete in bandwidth_update
drm/radeon: set correct CE ram size for CIK
drm/i915: safeguard against too high minimum brightness
drm/i915: vlv: fix gunit HW state corruption during S4 suspend
drm/i915: Disable caches for Global GTT.
This will fix no sound in Linux system after reboot from windows.
Change log:
- alc662_fill_coef() is replaced with alc_fill_eapd_coef_idx()
and move into alc_auto_init_amp().
- For ALC262, ALC267, ALC268, ALC269, ALC233, ALC255, ALC280, ALC282,
ALC283, ALC284, ALC285, ALC286, ALC288, ALC290, ALC292, ALC293, ALC294,
ALC668, ALC888VC, ALC888VD, ALC891, ALC892, ALC898 and ALC1150, add update
COEF control for EAPD setting.
- Remove alc269_fill_coef() for update EAPD control line.
ADDITIONAL NOTE:
Many Realtek cdoecs have a COEF bit to switch the master amp control
between COEF and EAPD. Windows drivers seem using COEF while we use
EAPD, which is more standard. As a result, some system suffer from
the silent output when booting after Windows. This patch sets the
COEF bits on the relevant codecs properly to switch to EAPD control.

Audit rules disappear when an inode they watch is evicted from the cache.
This is likely not what we want.
The guilty commit is "fsnotify: allow marks to not pin inodes in core",
which didn't take into account that audit_tree adds watches with a zero
mask.
Adding any mask should fix this.
