Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big set of USB and Thunderbolt patches for 5.14-rc1.

  Nothing major here just lots of little changes for new hardware and
  features. Highlights are:

   - more USB 4 support added to the thunderbolt core

   - build warning fixes all over the place

   - usb-serial driver updates and new device support

   - mtu3 driver updates

   - gadget driver updates

   - dwc3 driver updates

   - dwc2 driver updates

   - isp1760 host driver updates

   - musb driver updates

   - lots of other tiny things.

  Full details are in the shortlog.

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