Merge tag 'usb-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/PHY/Thunderbolt driver updates from Greg KH:
 "Here is the big set of USB, PHY, and Thunderbolt driver updates for
  5.10-rc1.

  Lots of tiny different things for these subsystems are in here,
  including:

   - phy driver updates

   - thunderbolt / USB 4 updates and additions

   - USB gadget driver updates

   - xhci fixes and updates

   - typec driver additions and updates

   - api conversions to various drivers for core kernel api changes

   - new USB control message functions to make it harder to get wrong,
     as found by syzbot (took 2 tries to get it right)

   - lots of tiny USB driver fixes and updates all over the place

  All of these have been in linux-next for a while, with the exception
  of the last "obviously correct" patch that updated a FALLTHROUGH
  comment that got merged last weekend"
