Merge tag 'usb-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB and Thunderbolt updates from Greg KH:
 "Here is the big set of USB and Thunderbolt driver changes for
  5.17-rc1.

  Nothing major in here, just lots of little updates and cleanups. These
  include:

   - some USB header fixes picked from Ingo's header-splitup work

   - more USB4/Thunderbolt hardware support added

   - USB gadget driver updates and additions

   - USB typec additions (includes some acpi changes, which were acked
     by the ACPI maintainer)

   - core USB fixes as found by syzbot that were too late for 5.16-final

   - USB dwc3 driver updates

   - USB dwc2 driver updates

   - platform_get_irq() conversions of some USB drivers

   - other minor USB driver updates and additions

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