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

Pull HID subsystem updates from Jiri Kosina:
 "HID subsystem and drivers update. Highlights:

   - new support of a group of Win7/Win8 multitouch devices, from
     Benjamin Tissoires

   - fix for compat interface brokenness in uhid, from Dmitry Torokhov

   - conversion of drivers to use hid_driver helper, by H Hartley
     Sweeten

   - HID over I2C transport received ACPI enumeration support, written
     by Mika Westerberg

   - there is an ongoing effort to make HID sensor hubs independent of
     USB transport.  The first self-contained part of this work is
     provided here, done by Mika Westerberg

   - a few smaller fixes here and there, support for a couple new
     devices added"
