OK, please see review-dvhart-mellanox-v12 on infradead or github. I've verified
this passes a clean C=1 (sparse) build at each patch. I believe this is in a

If you still want to move the dev_err messages out of the create function, we
can do that separately. Let's get this merged so we can move forward.
