Merge tag 'usb-4.14-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are a handful of USB driver fixes for 4.14-rc5.

  There is the "usual" usb-serial fixes and device ids, USB gadget
  fixes, and some more fixes found by the fuzz testing that is happening
  on the USB layer right now.

  All of these have been in my tree this week with no reported issues"
