Pull USB / Thunderbolt updates from Greg KH:
 "Here is the big set of USB and Thunderbolt patches for 5.15-rc1.

  Nothing huge in here, just lots of constant forward progress on a
  number of different drivers and hardware support:

   - more USB 4/Thunderbolt support added

   - dwc3 driver updates and additions

   - usb gadget fixes and addtions for new types

   - udc gadget driver updates

   - host controller updates

   - removal of obsolete drivers

   - other minor driver updates

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