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

Pull input subsystem fixes from Dmitry Torokhov:
 "A couple of driver/build fixups and also redone quirk for Synaptics
  touchpads on Lenovo boxes (now using PNP IDs instead of DMI data to
  limit number of quirks)"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: synaptics - change min/max quirk table to pnp-id matching
  Input: synaptics - add a matches_pnp_id helper function
  Input: synaptics - T540p - unify with other LEN0034 models
  Input: synaptics - add min/max quirk for the ThinkPad W540
  Input: ambakmi - request a shared interrupt for AMBA KMI devices
  Input: pxa27x-keypad - fix generating scancode
  Input: atmel-wm97xx - only build for AVR32
  Input: fix ps2/serio module dependency
