From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> dpcm_fe_dai_startup() (= A) calls dpcm_set_fe_runtime() (= B) to setup DPCM runtime. 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 dpcm_runtime_setup_fe() (= X), and setups BE by dpcm_runtime_merge_xxx() (= Y). (B) static void dpcm_set_fe_runtime(...) { ... (X) dpcm_runtime_setup_fe(...); ^ dpcm_runtime_merge_format(...); (Y) dpcm_runtime_merge_chan(...); v dpcm_runtime_merge_rate(...); } These means that the function which is called as xxx_fe_xxx() is setups both FE and BE. This is confusable and can be hot bed for bug. This patch renames unclear dpcm_runtime_merge_xxx() (= Y) to more clear dpcm_runtime_setup_be_xxx().
