It seems I was too quick to declare success, unfortunately.
It's a pity :-<
Then we may try another approach. Instead of backport tons of patches, revert / work around the change that caused the probe failure.
I'm building another test kernel in OBS home:tiwai:bsc1173085-3 repo with a downstream patch that allows the default MAC version assignment for your chip. It's a very small change and less intrusive. Let's see whether it works.
