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

Pull more input updates from Dmitry Torokhov:
 "The second round of updates for the input subsystem.

  Updates to ALPS an bfin_roraty drivers and a couple oother fixups"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: psmouse - use IS_ENABLED instead of homegrown code
  Input: bfin_rotary - introduce open and close methods
  Input: bfin_rotary - convert to use managed resources
  Input: bfin_rotary - use generic IO functions
  Input: bfin_rotary - move pin lists into into platform data
  Input: bfin_rotary - move platform header to linux/platform_data
  Input: bfin_rotary - mark suspend and resume code as __maybe_unused
  Input: bfin_rotary - fix potential oops in interrupt handler
  Input: ALPS - move v7 packet info to Documentation and v6 packet info
  Input: ALPS - fix confusing comment in protocol data
  Input: ALPS - do not mix trackstick and external PS/2 mouse data
  Input: ALPS - fix trackstick detection on some Dell Latitudes
  Input: ALPS - consolidate setting protocol parameters
  Input: ALPS - split protocol data from model info
  Input: ALPS - make Rushmore a separate protocol
  Input: ALPS - renumber protocol numbers
  Input: adi - remove an unnecessary check
  Input: pxa27x_keypad - remove an unneeded NULL check
  Input: soc_button_array - use "Windows" key for "Home"
