Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input layer updates from Dmitry Torokhov:
- evdev interface has been adjusted to extend the life of timestamps on
32 bit systems to the year of 2108
- Synaptics RMI4 driver's PS/2 guest handling ha beed updated to
improve chances of detecting trackpoints on the pass-through port
- mms114 touchcsreen controller driver has been updated to support
generic device properties and work with mms152 cntrollers
- Goodix driver now supports generic touchscreen properties
- couple of drivers for AVR32 architecture are gone as the architecture
support has been removed from the kernel
- gpio-tilt driver has been removed as there are no mainline users and
the driver itself is using legacy APIs and relies on platform data
- MODULE_LINECSE/MODULE_VERSION cleanups
