Merge tag 'usb-4.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB updates from Greg KH:
 "Here is the big USB patchset for 4.4-rc1.

  As usual, most of the changes are in the gadget subsystem, and we
  removed a host controller for a device that is no longer in existance,
  and probably never was even made public.  There is also other minor
  driver updates and new device ids, full details in the changelog.

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