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

   - PHY driver additions and cleanups

   - Thunderbolt minor additions and fixes

   - USB MIDI 2 gadget support added

   - dwc3 driver updates and additions

   - Removal of some old USB wireless code that was missed when that
     codebase was originally removed a few years ago, cleaning up some
     core USB code paths

   - USB core potential use-after-free fixes that syzbot from different
     people/groups keeps tripping over

   - typec updates and additions

   - gadget fixes and cleanups

   - loads of smaller USB core and driver cleanups all over the place

  Full details are in the shortlog. All of these have been in linux-next
  for a while with no reported problems"
