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

Pull HID updates from Jiri Kosina:

 - quirk for devices that need to be pulled in much more aggresive way
   than mandated, by Johan Hovold

 - robustification of sanity checking of incoming reports in RMI driver,
   by Benjamin Tissoires

 - fixes, updates, and new HW support to SONY driver, by Frank Praznik

 - port of uHID to the new transport layer layout, by David Herrmann

 - robustification of Clear-Halt/reset in USB HID, by Alan Stern

 - native support for hopefully any future HID compliant wacom tablet.
   Those found on the various laptops (ISDv4/5) already are HID
   compliant and they should work in the future without any modification
   of the kernel.  Written by Benjamin Tissoires.

 - a lot more simple fixes and device ID additions all over the place
