Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/hid
Pull HID subsystem updates from Jiri Kosina:
"Apart from various driver updates and added support for a number of
new devices (mostly multitouch ones, but not limited to), there is one
change that is worth pointing out explicitly: creation of HID device
groups and proper autoloading of hid-multitouch, implemented by Henrik
Rydberg."
