Merge tag 'usb-3.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB updates from Greg KH:
 "Here is the big USB driver update for 3.17-rc1.

  Loads of gadget driver changes in here, including some big file
  movements to make things easier to manage over time.  There's also the
  usual xhci and uas driver updates, and a handful of other changes in
  here.  The changelog has the full details.

  All of these have been in linux-next for a while"
