But in reality, these are very similar but different implementation. We shouldn't have duplicated and confusing implementation. snd_soc_register_dai() is now used from topology. But to reduce duplicated code, it should be used from _dais(), too. Because of topology side specific reason, it is calling snd_soc_dapm_new_dai_widgets(), but it is not needed _dais() side. This patch factorizes snd_soc_register_dai() to topology / _dais() common part, and topology specific part. And do topology specific part at soc-topology.
