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

Pull input subsystem updates from Dmitry Torokhov:

 - updated support for Synaptics RMI4 devices, including support for
   SMBus controllers, firmware update support, sensor tuning, and PS/2
   guest support

 - ALPS driver now supports tracksticks on SS5 controllers

 - i8042 now uses chassis info to skip selftest on Asus laptops as list
   of individual models became too unwieldy

 - miscellaneous fixes to other drivers

* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (67 commits)
