Browse source 
Here are 2 small USB driver fixes that resolve some reported regressions
 and one new device quirk.  Specifically these are:
   - new quirk for Alcor Link AK9563 smartcard reader
   - revert of u_ether gadget change in 6.2-rc1 that caused problems
   - typec pin probe fix
 
 All of these have been in linux-next with no reported problems.
