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

Pull HID updates from Jiri Kosina:

 - rumble support for Xbox One S, from Andrey Smirnov

 - high-resolution support for Logitech mice, from Harry Cutts

 - support for recent devices requiring the HID parse to be able to cope
   with tag report sizes > 256
