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

Pull HID subsystem updates from Jiri Kosina:

 1) Support for HID over I2C bus has been added by Benjamin Tissoires.
    ACPI device discovery is still in the works.

 2) Support for Win8 Multitiouch protocol is being added, most work done
    by Benjamin Tissoires as well

 3) EIO/ERESTARTSYS is fixed in hiddev/hidraw, fixes by Andrew Duggan
    and Jiri Kosina

 4) ION iCade driver added by Bastien Nocera

 5) Support for a couple new Roccat devices has been added by Stefan
    Achatz

 6) HID sensor hubs are now auto-detected instead of having to list all
    the VID/PID combinations in the blacklist array

 7) other random fixes and support for new device IDs
