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

Pull input updates from Dmitry Torokhov:

 - support for inhibiting input devices at request from userspace. If a
   device implements open/close methods, it can also put device into low
   power state. This is needed, for example, to disable keyboard and
   touchpad on convertibles when they are transitioned into tablet mode

 - now that ordinary input devices can be configured for polling mode,
   dedicated input polling device implementation has been removed

 - GTCO tablet driver has been removed, as it used problematic custom
   HID parser, devices are EOL, and there is no interest from the
   manufacturer

 - a new driver for Dialog DA7280 haptic chips has been introduced

 - a new driver for power button on Dell Wyse 3020

 - support for eKTF2132 in ektf2127 driver

 - support for SC2721 and SC2730 in sc27xx-vibra driver

 - enhancements for Atmel touchscreens, AD7846 touchscreens, Elan
   touchpads, ADP5589, ST1232 touchscreen, TM2 touchkey drivers

 - fixes and cleanups to allow clean builds with W=1
