Merge tag 'usb-4.18-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here is a number of USB gadget and other driver fixes for 4.18-rc3.

  There's a bunch of them here, most of them being gadget driver and
  xhci host controller fixes for reported issues (as normal), but there
  are also some new device ids, and some fixes for the typec code.

  There is an acpi core patch in here that was acked by the acpi
  maintainer as it is needed for the typec fixes in order to properly
  solve a problem in that driver.

  All of these have been in linux-next this week with no reported
  issues"
