Merge tag 'usb-4.6-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are some USB fixes and new device ids for 4.6-rc3.

  Nothing major, the normal USB gadget fixes and usb-serial driver ids,
  along with some other fixes mixed in.  All except the USB serial ids
  have been tested in linux-next, the id additions should be fine as
  they are 'trivial'"
