Browse Source 
Here are some small USB driver fixes for reported problems for 6.9-rc7.
 Included in here are:
   - usb core fixes for found issues
   - typec driver fixes for reported problems
   - usb gadget driver fixes for reported problems
   - xhci build fixes
   - dwc3 driver fixes for reported issues
 
 All of these have been in linux-next this past week with no reported
 problems.
