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

Pull input subsystem updates from Dmitry Torokhov:
 "Two new drivers for Elan hardware (for I2C touchpad and touchscreen
  found in several Chromebooks and other devices), a driver for Goodix
  touch panel, and small fixes to Cypress I2C trackpad and other input
  drivers.

  Also we switched to use __maybe_unused instead of gating suspend/
  resume code with #ifdef guards to get better compile coverage"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (27 commits)
  Input: gpio_keys - fix warning regarding uninitialized 'button' variable
  Input: add support for Elan eKTH I2C touchscreens
  Input: gpio_keys - fix warning regarding uninitialized  'irq' variable
  Input: cyapa - use 'error' for error codes
  Input: cyapa - fix resuming the device
  Input: gpio_keys - add device tree support for interrupt only keys
  Input: amikbd - allocate temporary keymap buffer on the stack
  Input: amikbd - fix build if !CONFIG_HW_CONSOLE
  Input: lm8323 - missing error check in lm8323_set_disable()
  Input: initialize device counter variables with -1
  Input: initialize input_no to -1 to avoid subtraction
  Input: i8042 - do not try to load on Intel NUC D54250WYK
  Input: atkbd - correct MSC_SCAN events for force_release keys
  Input: cyapa - switch to using managed resources
  Input: lifebook - use "static inline" instead of "inline" in lifebook.h
  Input: touchscreen - use __maybe_unused instead of ifdef around suspend/resume
  Input: mouse - use __maybe_unused instead of ifdef around suspend/resume
  Input: misc - use __maybe_unused instead of ifdef around suspend/resume
  Input: cap11xx - support for irq-active-high option
  Input: cap11xx - add support for various cap11xx devices
