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"
