Pull USB fixes from Greg KH:
"Here are some small reverts and fixes for USB drivers for issues that
came up during the 5.16-rc1 merge window.
These include:
- two reverts of xhci and USB core patches that are causing problems
in many systems.
- xhci 3.1 enumeration delay fix for systems that were having
problems.
All three of these have been in linux-next all week with no reported
issues"
