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."
