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

Pull HID updates from Jiri Kosina:

 - quite a few firmware fixes for RMI driver by Andrew Duggan

 - huion and uclogic drivers have been substantially overlaping in
   functionality laterly.  This redundancy is fixed by hid-huion driver
   being merged into hid-uclogic; work done by Benjamin Tissoires and
   Nikolai Kondrashov

 - i2c-hid now supports ACPI GPIO interrupts; patch from Mika Westerberg

 - Some of the quirks, that got separated into individual drivers, have
   historically had EXPERT dependency.  As HID subsystem matured (as
   well as the individual drivers), this made less and less sense.  This
   dependency is now being removed by patch from Jean Delvare

 - Logitech lg4ff driver received a couple of improvements for mode
   switching, by Michal Malý

 - multitouch driver now supports clickpads, patches by Benjamin
   Tissoires and Seth Forshee

 - hid-sensor framework received a substantial update; namely support
   for Custom and Generic pages is being added; work done by Srinivas
   Pandruvada

 - wacom driver received substantial update; it now supports
   i2c-conntected devices (Mika Westerberg), Bamboo PADs are now
   properly supported (Benjamin Tissoires), much improved battery
   reporting (Jason Gerecke) and pen proximity cleanups (Ping Cheng)

 - small assorted fixes and device ID additions
