These happen at v3.14. But, maybe because of branch merge conflict or something similar happen then, soc_pcm_close() still has old settings (care only dai->rate, doesn't care dai->channels/sample_bits). This is 100% duplicated operation. This patch removes soc_pcm_close() side operation which supposed to already moved to soc_pcm_hw_free().
