Merge tag 'usb-6.9-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 6.9-rc1. Lots
  of tiny changes and forward progress to support new hardware and
  better support for existing devices. Included in here are:

   - Thunderbolt (i.e. USB4) updates for newer hardware and uses as more
     people start to use the hardware

   - default USB authentication mode Kconfig and documentation update to
     make it more obvious what is going on

   - USB typec updates and enhancements

   - usual dwc3 driver updates

   - usual xhci driver updates

   - function USB (i.e. gadget) driver updates and additions

   - new device ids for lots of drivers

   - loads of other small updates, full details in the shortlog

  All of these, including a "last minute regression fix" have been in
  linux-next with no reported issues"
