Pull USB / Thunderbolt fixes from Greg KH:
 "Here are a number of tiny USB and Thunderbolt driver fixes for
  5.13-rc4.

  They consist of:

   - thunderbolt fixes for some NVM bound issues

   - xhci fixes for reported problems

   - control-request fixups

   - documentation build warning fixes

   - new usb-serial driver device ids

   - typec bugfixes for reported issues

   - usbfs warning fixups (could be triggered from userspace)

   - other tiny fixes for reported problems.

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