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

Pull HID updates from Jiri Kosina:
 - substantial cleanup of the generic and transport layers, in the
   direction of an ultimate goal of making struct hid_device completely
   transport independent, by Benjamin Tissoires
 - cp2112 driver from David Barksdale
 - a lot of fixes and new hardware support (Dualshock 4) to hid-sony
   driver, by Frank Praznik
 - support for Win 8.1 multitouch protocol by Andrew Duggan
 - other smaller fixes / device ID additions
