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

Browse Source 
Pull input updates from Dmitry Torokhov:
 "An update to Synaptics PS/2 driver to handle "ForcePads" (currently
  found in HP EliteBook 1040 laptops), a change for Elan PS/2 driver to
  detect newer touchpads, bunch of devices get annotated as Trackpoint
  and/or Pointer to help userspace classify and handle them, plus
  assorted driver fixes"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: serport - add compat handling for SPIOCSTYPE ioctl
  Input: atmel_mxt_ts - fix double free of input device
  Input: synaptics - add support for ForcePads
  Input: matrix_keypad - use request_any_context_irq()
  Input: atmel_mxt_ts - downgrade warning about empty interrupts
  Input: wm971x - fix typo in module parameter description
  Input: cap1106 - fix register definition
  Input: add missing POINTER / DIRECT properties to a bunch of drivers
  Input: add INPUT_PROP_POINTING_STICK property
  Input: elantech - fix detection of touchpad on ASUS s301l
