Pull USB merge for 3.4-rc1 from Greg KH:
 "Here's the big USB merge for the 3.4-rc1 merge window.

  Lots of gadget driver reworks here, driver updates, xhci changes, some
  new drivers added, usb-serial core reworking to fix some bugs, and
  other various minor things.

  There are some patches touching arch code, but they have all been
  acked by the various arch maintainers."
