Merge tag 'usb-6.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB / Thunderbolt driver updates from Greg KH:
"Here is the big set of USB and Thunderbolt driver updates for 6.5-rc1.
Included in here are:
- Lots of USB4/Thunderbolt additions and updates for new hardware
types and fixes as people are starting to get access to the
hardware in the wild
- new gadget controller driver, cdns2, added
- new typec drivers added
- xhci driver updates
- typec driver updates
- usbip driver fixes
- usb-serial driver updates and fixes
- lots of smaller USB driver updates
All of these have been in linux-next for a while with no reported
problems"
