This is still wrong as you are allowing "<prefix>label" for property
names. I think you want something like this:
ret = snd_soc_of_parse_card_name(card, "label");
if (ret < 0) {
char prop[128];
snprintf(prop, sizeof(prop), "%sname", prefix);
/* Parse the card name from DT */
ret = snd_soc_of_parse_card_name(card, prop);
if (ret < 0)
return ret;
}
