ASoC: soc-pcm: fixup snd_pcm_limit_hw_rates() timing
soc-pcm has snd_pcm_limit_hw_rates() which determine rate_min/rate_max. It updates runtime->hw.rate_min/max (A) based on hw->rates (B). int snd_pcm_limit_hw_rates(...) { int i; for (...) { (B) if (runtime->hw.rates & (1 << i)) { (A) runtime->hw.rate_min = ... break; } } for (...) { (B) if (runtime->hw.rates & (1 << i)) { (A) runtime->hw.rate_max = ... break; } } return 0; } This means, setup order is 1) set hw->rates 2) call snd_pcm_limit_hw_rates() 3) update hw->rate_min/max soc_pcm_init_runtime_hw() is calling it in good order static void soc_pcm_init_runtime_hw(xxx) { ... 1) hw->rates = snd_pcm_rate_mask_intersect(...); 2) snd_pcm_limit_hw_rates(...); 3) hw->rate_min = max(...); hw->rate_min = max(...); hw->rate_max = min_not_zero(...); hw->rate_max = min_not_zero(...); } But, dpcm_fe_dai_startup() is not. static int dpcm_fe_dai_startup(xxx) { ... 1) 3) dpcm_set_fe_runtime(...); 2) snd_pcm_limit_hw_rates(...); ... } More detail of dpcm_set_fe_runtime() is static void dpcm_set_fe_runtime() { ... for_each_rtd_cpu_dais(rtd, i, cpu_dai) { ... 3) 1) dpcm_init_runtime_hw(...); } ... 3) 1) dpcm_runtime_merge_rate(...); } This patch fixup these into static void dpcm_set_fe_runtime() { ... for_each_rtd_cpu_dais(rtd, i, cpu_dai) { ... 1) 2) 3) dpcm_init_runtime_hw(...); } ... 1) 2) 3) dpcm_runtime_merge_rate(...); } static int dpcm_fe_dai_startup(xxx) { ... dpcm_set_fe_runtime(...); - snd_pcm_limit_hw_rates(...); ... } Link: https://lore.kernel.org/r/87k15l7ewd.wl-kuninori.morimoto.gx@renesas.comSigned-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Link: https://lore.kernel.org/r/8735ytaig8.wl-kuninori.morimoto.gx@renesas.comSigned-off-by: Mark Brown <broonie@kernel.org>
