Hi Mark, again
sorry previous was not good question
- if (!card->name)
card->name = card->dai_link->name;This will unconditionally defererence dai_link but it's optional - we can have analogue only cards.
This is not new feature. Current simple-card already has it.
Right, but simple-card does need DAIs IIRC while this is intended to be more general. All it needs is a check before the dereference to be safe so it's trivial to handle.
Sorry, I'm not 100% understand. Do you mean we don't need handle card->name ? (= we should remove above ?) If so, we can't register card on simple-card. Because snd_soc_register_card() requests it.
This function tries to get card name from snd_soc_of_parse_card_name(). and it tries to set card->name from dai_link if card still doesn't have name. So, above is optional 2nd try. Or, do you mean this if (!card->name) can goes to simple-card, instead of utils ? I have no objection about it , but it can be double handling ? Because other simple family have same situation.
