This looks like you're trying to write a switch statement. It's also
somewhat unclear to me that this should be in a machine driver and not
in a CODEC/aux driver that gets pulled in by a machine driver, I can't
be entirely sure what this is controlling.

headsets sound external too?

We parse the DT here and then...

...this other bit of DT here.

If setting card->dev does anything there something is broken, and in
general it's just better form to not special case probe deferral.
