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

Pull input updates from Dmitry Torokhov:

 - an update to Elan touchpad SMBus driver to fetch device parameters
   (size, resolution) while it is still in PS/2 mode, before switching
   over to SMBus, as in that mode some devices return garbage dimensions

 - update to iforce joystick driver

 - miscellaneous driver fixes

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (48 commits)
  Input: gpio_keys_polled - allow specifying name of input device
  Input: edt-ft5x06 - simplify event reporting code
  Input: max77650-onkey - add MODULE_ALIAS()
  Input: atmel_mxt_ts - fix leak in mxt_update_cfg()
  Input: synaptics - enable SMBUS on T480 thinkpad trackpad
  Input: atmel_mxt_ts - fix -Wunused-const-variable
  Input: joydev - extend absolute mouse detection
  HID: quirks: Refactor ELAN 400 and 401 handling
  Input: elan_i2c - export the device id whitelist
  Input: edt-ft5x06 - use get_unaligned_be16()
  Input: iforce - add the Saitek R440 Force Wheel
  Input: iforce - use unaligned accessors, where appropriate
  Input: iforce - drop couple of temps from transport code
  Input: iforce - drop bus type from iforce structure
  Input: iforce - use DMA-safe buffores for USB transfers
  Input: iforce - allow callers supply data buffer when fetching device IDs
  Input: iforce - only call iforce_process_packet() if initialized
  Input: iforce - signal command completion from transport code
  Input: iforce - do not combine arguments for iforce_process_packet()
  Input: iforce - factor out hat handling when parsing packets
