Merge tag 'usb-5.12-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are a few small USB driver fixes for 5.12-rc6 to resolve reported
  problems.

  They include:

   - a number of cdc-acm fixes for reported problems. It seems more
     people are using this driver lately...

   - dwc3 driver fixes for reported problems, and fixes for the fixes :)

   - dwc2 driver fixes for reported issues.

   - musb driver fix.

   - new USB quirk additions.

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