Merge tag 'usb-5.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/Thunderbolt updates from Greg KH:
"Here is the large set of USB and Thunderbolt patches for 5.9-rc1.
Nothing really magic/major in here, just lots of little changes and
updates:
- clean up language usages in USB core and some drivers
- Thunderbolt driver updates and additions
- USB Gadget driver updates
- dwc3 driver updates (like always...)
- build with "W=1" warning fixups
- mtu3 driver updates
- usb-serial driver updates and device ids
- typec additions and updates for new hardware
- xhci debug code updates for future platforms
- cdns3 driver updates
- lots of other minor driver updates and fixes and cleanups
All of these have been in linux-next for a while with no reported
issues"
