Hi Takashi Thank you for feedback > Actually the question is whether we need snd_pcm_limit_hw_rates() call > or not. The current code in soc_pcm_init_runtime_hw() assumes that > each cpu and codec dais already set the proper rate_min and rate_max, > and narrow the range accordingly.

OK, it is same as my understanding. I want to do (so far) is just cleanup. I will fixup/cleanup it. I'm posting ALSA SoC cleanup patches to ML. This fixup/cleanup will be added to my ALSA-SoC-cleanup-patch-queue Thank you for your help !!
