Merge tag 'usb-5.16-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB fixes from Greg KH:
 "Here are a number of small USB driver fixes for reported problems.
  They include:

   - dwc2 driver fixes

   - xhci driver fixes

   - cdnsp driver fixes

   - typec driver fix

   - gadget u_ether driver fix

   - new quirk additions

   - usb gadget endpoint calculation fix

   - usb serial new device ids

   - revert of a xhci-dbg change that broke early debug booting

  All changes, except for the revert, have been in linux-next with no
  reported problems. The revert was from yesterday, and it was reported
  by the developers affected that it resolved their problem"
