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)"

Input: xen-kbdfront - free grant table entry in xenkbd_disconnect_backend
Input: alps - fix v4 button press recognition
Input: i8042 - disable active multiplexing by default
Input: i8042 - add noloop quirk for Asus X750LN
Input: synaptics - gate forcepad support by DMI check
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
Input: adp5588-keys - cancel workqueue in failure path
