Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:
 "A few drivers were updated with device tree bindings and others got a
  few small cleanups and fixes."

Fix trivial conflict in drivers/input/keyboard/omap-keypad.c due to
changes clashing with a whitespace cleanup.

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (28 commits)
  Input: wacom - mark Intuos5 pad as in-prox when touching buttons
  Input: synaptics - adjust threshold for treating position values as negative
  Input: hgpk - use %*ph to dump small buffer
  Input: gpio_keys_polled - fix dt pdata->nbuttons
  Input: Add KD[GS]KBDIACRUC ioctls to the compatible list
  Input: omap-keypad - fixed formatting
  Input: tegra - move platform data header
  Input: wacom - add support for EMR on Cintiq 24HD touch
  Input: s3c2410_ts - make s3c_ts_pmops const
  Input: samsung-keypad - use of_get_child_count() helper
  Input: samsung-keypad - use of_match_ptr()
  Input: uinput - fix formatting
  Input: uinput - specify exact bit sizes on userspace APIs
  Input: uinput - mark failed submission requests as free
  Input: uinput - fix race that can block nonblocking read
  Input: uinput - return -EINVAL when read buffer size is too small
  Input: uinput - take event lock when fetching events from buffer
  Input: get rid of MATCH_BIT() macro
  Input: rotary-encoder - add DT bindings
  Input: rotary-encoder - constify platform data pointers
