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

Pull HID updates from Jiri Kosina:
 "The list of changes worth pointing out explicitly:

  - We are getting 'UHID', which is a new framework for implementing HID
    transport drivers in userspace (this is different from HIDRAW, which
    is transport-independent and provides report parsing facilities;
    uhid is for the other (transport) part of the pipeline).

    It's needed for (and currently being used by) Bluetooth-LowEnergy,
    as its specification mandates things we don't want in the kernel.

    Written by David Herrmann.

  - there have been quite a few bugs in runtime suspend/resume paths
    (probably never reported to actually happen in the wild, but still).
    Alan Stern fixed those.

  - a few other driver updates and fixes and random new device support."
