Now soc-core and soc-topology is using snd_soc_add_dai_link().
It sounds like dai_link function.
But, it creates new pcm_runtime (= rtd), and connect it to card.
The purpose is adding pcm_runtime, not dai_link.
this function seems to have 2 purposes, dai_link operations and
pcm_runtime creation.
int snd_soc_add_dai_link(struct snd_soc_card *card,
struct snd_soc_dai_link *dai_link)
{
/*
* Notify the machine driver for extra initialization
*/
if (card->add_dai_link)
card->add_dai_link(card, dai_link);
