(A) static void dpcm_init_runtime_hw(...) { ... ^ if (runtime->hw.formats) | (D1) runtime->hw.formats &= stream->formats; (D) else | (D2) runtime->hw.formats = stream->formats; v } (B) static void dpcm_set_fe_runtime(...) { ... (C) for_each_rtd_cpu_dais(rtd, i, cpu_dai) { ... (A) dpcm_init_runtime_hw(...); } } If this for_each_rtd_cpu_dais() loop (= C) calls dpcm_init_runtime_hw() (= A) multiple times, this means it is Multi-CPU. If we focus to format operation at (D), using mask (= D1) is understandable because it restricts unsupported format. But, enabling format when zero format case (= D2) is very strange, because it might enables unsupported format. This runtime->hw.formats is initialized by ULLONG_MAX at soc_pcm_hw_init(), thus becoming zero format means it can't use such format. And doing this strange format operation is only here. This patch removes strange format operation (= D2), and use standard soc_pcm_hw_update_format() for it.

From *naming point of view*, it sounds like setup function for FE. (A) static int dpcm_fe_dai_startup(...) { ... (B) dpcm_set_fe_runtime(...); ... } But in dpcm_set_fe_runtime() (= B), It setups FE by for_each loop (= X), and setups BE by dpcm_runtime_merge_xxx() (= Y).

This is confusable and can be hot bed for bug. To tidyup it, as 1st step, this patch adds new dpcm_runtime_setup_fe() for (X).
