Pull USB/Thunderbolt updates from Greg KH:
 "Here is the large set of USB and Thunderbolt patches for 5.9-rc1.

  Nothing really magic/major in here, just lots of little changes and
  updates:

   - clean up language usages in USB core and some drivers

   - Thunderbolt driver updates and additions

   - USB Gadget driver updates

   - dwc3 driver updates (like always...)

   - build with "W=1" warning fixups

   - mtu3 driver updates

   - usb-serial driver updates and device ids

   - typec additions and updates for new hardware

   - xhci debug code updates for future platforms

   - cdns3 driver updates

   - lots of other minor driver updates and fixes and cleanups

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