Pull input subsystem fixes from Dmitry Torokhov:
 "Miscellaneous driver fixes"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: psmouse - disable "palm detection" in the focaltech driver
  Input: psmouse - disable changing resolution/rate/scale for FocalTech
  Input: psmouse - ensure that focaltech reports consistent coordinates
  Input: psmouse - remove hardcoded touchpad size from the focaltech driver
  Input: tc3589x-keypad - set IRQF_ONESHOT flag to ensure IRQ request
  Input: ALPS - fix memory leak when detection fails
  Input: sun4i-ts - add thermal driver dependency
  Input: cyapa - remove superfluous type check in cyapa_gen5_read_idac_data()
  Input: cyapa - fix unaligned functions redefinition error
  Input: mma8450 - add parent device

Apparently, the threshold for large contact area seems to be rather low on
some devices, causing the touchpad to frequently freeze during normal
usage. Because we do now know how we are supposed to use the value in
question, this commit just drops the related code completely.

These PS/2 commands make some touchpads stop responding, so this commit
adds some dummy functions to replace the generic implementation. Because
scale changes were not encapsulated in a method of struct psmouse yet, this
commit adds a method set_scale to psmouse.

We don't know whether x_max or y_max really hold the maximum possible
coordinates, and we don't know for sure whether we correctly interpret the
coordinates sent by the touchpad, so we clamp the reported values to
prevent confusion in userspace code.

The size has in most cases already been fetched from the touchpad, the
hardcoded values should have been removed.

Since commit 1c6c69525b40eb76de8adf039409722015927dc3 ("genirq: Reject
bogus threaded irq requests") threaded IRQs without a primary handler
need to be requested with IRQF_ONESHOT, otherwise the request will fail.

Currently, plat->irqtype is only set to IRQF_TRIGGER_FALLING.  This
patch sets the ONESHOT flag directly in request_threaded_irq() to
enforce the flag without being affected by future changes to
plat->irqtype.

The sun4i-ts driver has had a dependency on the thermal code
with the addition of the thermal zone sensor support, but this
is not currently enforced in Kconfig, so with TOUCHSCREEN_SUN4I=y,
THERMAL=m and THERMAL_OF=y we get

drivers/built-in.o: In function `sun4i_ts_remove':
:(.text+0x2376f4): undefined reference to `thermal_zone_of_sensor_unregister'
drivers/built-in.o: In function `sun4i_ts_probe':
:(.text+0x237a94): undefined reference to `thermal_zone_of_sensor_register'
:(.text+0x237c00): undefined reference to `thermal_zone_of_sensor_unregister'

We need the dependency on THERMAL in order to ensure that this
driver becomes a loadable module if the thermal support itself
is modular, while the dependency on THERMAL_OF is a runtime
dependency and the driver will still build if it is missing.
It is entirely possible to build sun4i-ts without THERMAL_OF
just to use the hwmon sensors and/or touchscreen.

drivers/input/mouse/cyapa_gen5.c: In function ‘cyapa_gen5_read_idac_data’:
drivers/input/mouse/cyapa_gen5.c:1876: warning: ‘max_element_cnt’ may be used uninitialized in this function
drivers/input/mouse/cyapa_gen5.c:1873: warning: ‘offset’ may be used uninitialized in this function

If *data_size is non-zero, and idac_data_type contains an unknown type,
max_element_cnt and offset will be uninitialized, and the loop will
process non-existing data.

However, this cannot happen (for now), as there's a test for unknown
types at the top of cyapa_gen5_read_idac_data().

As no "if ... else if ..." is used in other places, remove the
superfluous "if" to silence the compiler warning.

Use asm/unaligned.h instead of linux/unaligned/access_ok.h header file to
fix compiling issues such as following while doing cross platform
compiling:

"include/linux/unaligned/access_ok.h:7:19: error: redefinition of
 'get_unaligned_le16'
...
include/linux/unaligned/le_struct.h:6:19: note: previous definition of
