Merge tag 'usb-5.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY/Thunderbolt driver updates from Greg KH:
"Here is the big set of USB, PHY, and Thunderbolt driver updates for
5.10-rc1.
Lots of tiny different things for these subsystems are in here,
including:
- phy driver updates
- thunderbolt / USB 4 updates and additions
- USB gadget driver updates
- xhci fixes and updates
- typec driver additions and updates
- api conversions to various drivers for core kernel api changes
- new USB control message functions to make it harder to get wrong,
as found by syzbot (took 2 tries to get it right)
- lots of tiny USB driver fixes and updates all over the place
All of these have been in linux-next for a while, with the exception
of the last "obviously correct" patch that updated a FALLTHROUGH
comment that got merged last weekend"
