soc_new_pcm() implementation is very long / verbose / complex, thus, it is very difficult to read. If we read it carefully, we can notice that it is consisted by
int soc_new_pcm(...) { (1) judging playback/caputre part (2) creating the PCM part (3) setup pcm/rtd part }
This patch adds new soc_create_pcm() for (2) part and offload it from snd_pcm_new().
