Merge tag 'usb-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB updates from Greg KH:
 "Here's the big USB 3.11-rc1 merge request.

  Lots of gadget and finally, chipidea driver updates (they were much
  needed), along with a new host controller driver, lots of little
  serial driver fixes, the removal of the 255 usb-serial device
  limitation, and a variety of other minor things.

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