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

Pull second round of input updates from Dmitry Torokhov:
 "Mostly simple bug fixes, although we do have one brand new driver for
  Microchip AR1021 i2c touchscreen.

  Also there is the change to stop trying to use i8042 active
  multiplexing by default (it is still possible to activate it via
  i8042.nomux=0 on boxes that implement it)"

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input:
  Input: xpad - add Thrustmaster as Xbox 360 controller vendor

  Input: Add Microchip AR1021 i2c touchscreen
  Input: cros_ec_keyb - add of match table
  Input: serio - avoid negative serio device numbers
  Input: avoid negative input device numbers
  Input: automatically set EV_ABS bit in input_set_abs_params
