Merge tag 'usb-6.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

Pull USB and Thunderbolt driver updates from Greg KH:
 "Here is the large set of USB and Thunderbolt driver changes for
  6.2-rc1. Overall, thanks to the removal of a driver, more lines were
  removed than added, a nice change. Highlights include:

   - removal of the sisusbvga driver that was not used by anyone anymore

   - minor thunderbolt driver changes and tweaks

   - chipidea driver updates

   - usual set of typec driver features and hardware support added

   - musb minor driver fixes

   - fotg210 driver fixes, bringing that hardware back from the "dead"

   - minor dwc3 driver updates

   - addition, and then removal, of a list.h helper function for many
     USB and other subsystem drivers, that ended up breaking the build.
     That will come back for 6.3-rc1, it missed this merge window.

   - usual xhci updates and enhancements

   - usb-serial driver updates and support for new devices

   - other minor USB driver updates

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