Merge tag 'usb-4.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY driver updates from Greg KH:
 "Here is the large USB and PHY driver update for 4.14-rc1.

  Not all that exciting, a few new PHY drivers, the usual mess of gadget
  driver updates and fixes, and of course, xhci updates to try to tame
  that beast.

  A number of usb-serial updates and other small fixes all over the USB
  driver tree are in here as well. Full details are in the shortlog.

  All of these have been in linux-next for a while with no reported
  issues"
