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"
