USB fixes for 5.7-rc3
Here are a number of USB driver fixes for 5.7-rc3.
Nothing huge, just the usual collection of:
- xhci fixes
- gadget driver fixes
- syzkaller fuzzing fixes
- new device ids and DT bindings
- new quirks added for broken devices
A few of the gadget driver fixes show up twice here as they were applied
to my branch, and also by Felipe to his branch which I then pulled in as
we got out of sync a bit.
All of these have been in linux-next with no reported issues.
