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

Pull HID updates from Jiri Kosina:

 - a lot of Wacom driver updates; most notably second generation Intuos
   Pro is now supported, code from Aaron Armstrong Skomra and Jason
   Gerecke

 - Surface 3 and 4 Type Cover Pro support from Daniel Keller, Dennis
   Chen and Yuta Kobayashi

 - hid-rmi is now generic transport driver, used by synaptics-rmi4;
   Support the Lenovo Thinkpad X1 Tablet dock follows on top, from
   Andrew Duggan

 - a few misc bugfixes and improvements here and there
