Merge tag 'usb-3.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB driver update from Greg KH:
 "Here's the big USB driver update for 3.13-rc1.

  It includes the usual xhci changes, EHCI updates to get the scheduling
  of USB transactions working better, and a raft of gadget and musb
  updates as well.

  All of this has been in linux-next for a while with no reported
  issues"
