Greg,
I think this is the issue Michael ran into. I'd like him to test the 
fix
before it's pulled in.
Michael,
If you can test this on the branch you saw the issue in and give a
Tested-by if it works, that'd be great.
Unfortunately, now I'm triggering another WARN_ON() in
device_links_driver_bound():
   WARN_ON(link->status != DL_STATE_DORMANT);
I've attached two bootlog one based on linux-next-20200525 with this
patch applied and another one where your previous debug printfs are
applied, too.
Let me know, if you need any other debug outputs.
original bootlog with this patch:
