Pull USB updates from Greg KH:
 "Here's the big USB pull request for 3.14-rc1

  Lots of little things all over the place, and the usual USB gadget
  updates, and XHCI fixes (some for an issue reported by a lot of
  people).  USB PHY updates as well as chipidea updates and fixes.

  All of these have been in the linux-next tree with no reported issues"
