Merge tag 'usb-5.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB/Thunderbolt updates from Greg KH:
 "Here is the big set of USB and Thunderbolt changes for 5.18-rc1.

  Nothing major in here, just lots of little improvements and cleanups
  and new device support. Highlights are:

   - list iterator fixups for when we walk past the end of the list (a
     common problem that was cut/pasted in almost all USB gadget
     drivers)

   - xen USB driver "hardening" for malicious hosts

   - xhci driver updates and fixes for more hardware types

   - xhci debug cable fixes to make it actually work again

   - usb gadget audio driver improvements

   - usb gadget storage fixes to work with OS-X

   - lots of other small usb gadget fixes and updates

   - USB DWC3 driver improvements for more hardware types

   - Lots of other small USB driver improvements

   - DTS updates for some USB platforms

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