  the common USB drivers. Included in here are:

   - more xhci driver updates and fixes

   - Thunderbolt driver cleanups

   - usb serial driver updates

   - typec driver updates

   - USB tracepoint additions

   - dwc3 driver updates, including support for Apple hardware

   - lots of other smaller driver updates and cleanups

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