Merge tag 'usb-5.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB / Thunderbolt updates from Greg KH:
"Here is the big USB and thunderbolt pull request for 5.11-rc1.
Nothing major in here, just the grind of constant development to
support new hardware and fix old issues:
- thunderbolt updates for new USB4 hardware
- cdns3 major driver updates
- lots of typec updates and additions as more hardware is available
- usb serial driver updates and fixes
- other tiny USB driver updates
All have been in linux-next with no reported issues"
