USB driver fixes for 5.15-rc3

Browse Source 
Here are some USB driver fixes and new device ids for 5.15-rc3.
 
 They include:
 	- usb-storage quirk additions
 	- usb-serial new device ids
 	- usb-serial driver fixes
 	- USB roothub registration bugfix to resolve a long-reported
 	  issue
 	- usb gadget driver fixes for a large number of small things
 	- dwc2 driver fixes
 
 All of these have been in linux-next for a while with no reported
 issues.
