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

Pull input layer fixes from Dmitry Torokhov:
 "Second round of updates for the input subsystem.  Mostly small fixups
  to the code merged in the first round (atmel_mxt_ts, wacom) but also a
  smallish patch to xbox driver to support Xbox One controllers and a
  patch to better handle Synaptics profile sensors found in Cr-48
  Chromebooks that should not affect any other devices"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: edt-ft5x06 - remove superfluous assignment
  Input: xpad - add support for Xbox One controllers
  Input: atmel_mxt_ts - fix a few issues reported by Coverity
  Input: atmel_mxt_ts - split config update a bit
  Input: atmel_mxt_ts - simplify mxt_initialize a bit
  Input: joystick - use get_cycles on ARMv8
  Input: wacom - fix compiler warning if !CONFIG_PM
  Input: cap1106 - allow changing key mapping from userspace
  Input: synaptics - use firmware data for Cr-48
  Input: synaptics - properly initialize slots for semi-MT
  Input: MT - make slot cleanup callable outside mt_sync_frame()
  Input: atmel_mxt_ts - mXT224 DMA quirk was fixed in firmware v2.0.AA
