This looks pretty good, a couple of minor points below which should be

You shouldn't need to do this?  If you do need to do it we should make
it possible to do it from the card struct.

This should be devm_snd_soc_register_card() and you need to parse the
card name before registering it, otherwise the card might instantiate
before the name is set.

No need for any of the _set_drvdata() calls, the core does them and they
shouldn't make any difference anyway.
