Pull staging/IIO fixes from Grek KH: "Here are a few small staging and iio driver fixes for reported issues. The last one was cherry-picked from my -next branch to resolve a build warning that Arnd fixed, in his quest to be able to turn -Wmaybe-uninitialized back on again.

staging: nvec: remove managed resource from PS2 driver

2016-11-07T10:48:25Z

This basicly reverts commit e534f3e9 (staging:nvec: Introduce the use of the managed version of kzalloc). Serio struct should never by managed because it is refcounted. Doing so will lead to a double free oops on module remove.

Revert "staging: nvec: ps2: change serio type to passthrough"

2016-11-07T10:48:25Z

This reverts commit 36b30d6138f4677514aca35ab76c20c1604baaad. This is necessary to detect paz00 (ac100) touchpad properly as one speaking ETPS/2 protocol. Without it X.org's synaptics driver doesn't work as the touchpad is detected as an ImPS/2 mouse instead. Commit ec6184b1c717b8768122e25fe6d312f609cc1bb4 changed the way auto-detection is performed on ports marked as pass through and made the issue apparent. A pass through port is an additional PS/2 port used to connect a slave device to a master device that is using PS/2 to communicate with the host (so slave's PS/2 communication is tunneled over master's PS/2 link). "Synaptics PS/2 TouchPad Interfacing Guide" describes such a setup (PS/2 PASS-THROUGH OPTION section). Since paz00's embedded controller is not connected to a PS/2 port itself, the PS/2 interface it exposes is not a pass-through one.

drivers: staging: nvec: remove bogus reset command for PS/2 interface

2016-11-07T10:48:25Z

This command was sent behind serio's back and the answer to it was confusing atkbd probe function which lead to the elantech touchpad getting detected as a keyboard. To prevent this from happening just let every party do its part of the job. Signed-off-by: Paul Fertser Acked-by: Marc Dietrich Cc: stable # 3.4+ Signed-off-by: Greg Kroah-Hartman

staging: greybus: arche-platform: fix device reference leak

2016-11-07T10:45:42Z

Make sure to drop the device reference taken by of_find_device_by_node() before returning from arche_platform_change_state(). Note that this code is expected to be removed, but let's fix up the leak nonetheless. Fixes: 886aba558b9e ("greybus: arche-platform: Export fn to allow...")

staging: comedi: ni_tio: fix buggy ni_tio_clock_period_ps() return value

2016-11-07T10:45:42Z

`ni_tio_clock_period_ps()` used to return the clock period in picoseconds, and had a `BUG()` call for invalid cases. It was changed to pass the clock period back via a pointer parameter and return an error for the invalid cases. Unfortunately the code to handle user-specified clock sources with user-specified clock period is still returning the clock period the old way, which can lead to the caller not getting the clock period, or seeing an unexpected error. Fix it by passing the clock period via the pointer parameter and returning `0`.

staging: sm750fb: Fix bugs introduced by early commits

2016-11-07T09:27:40Z

Early commit 30ca5cb63c56965 ("staging: sm750fb: change definition of PANEL_PLANE_TL fields") and 27b047bbe1ee9c0 ("staging: sm750fb: change definition of PANEL_PLANE_BR fields") modify the register bit fields definitions. But the modifications are wrong, because the bit mask of "bit field 10:0" is not 0xeff, but 0x7ff. The wrong definition bugs makes display very strange.

Merge tag 'iio-fixes-for-4.9b' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus

2016-11-07T08:42:27Z

Second set of IIO fixes for the 4.9 cycle. Interestingly scale related fixes for accelerometers at both ends of the range. Obviously more varied devices turning up than we've seen before! * ad5933 - fix an uninitialized value in a return case that is winding up GCC. * hid sensors - missing pm function prevents hid rotations sensors from working on newer ISH hubs (works by luck on older ones) - increase of scale precision needed to fix a case where on a yoga 260 the reported scale is 0 (presumably a high precision but very low g sensor). * st_sensors - fix an issue seen with the hs3lis331dl where the range is much greater than previous devices (100's of g) and hence the per bit scale is greater than 1.
