Browse Source 
Here are some small USB driver fixes for some reported issues.  Included
 in here are:
   - typec driver bugfixes
   - u_serial gadget driver bugfix for much reported and discussed issue
   - dwc2 bugfixes
   - midi gadget driver bugfix
   - ehci-hcd driver bugfix
   - other small bugfixes
 
 All of these have been in linux-next for over a week with no reported
 issues.
