This can be used instead of deriving the value from other parameters. This is similar to e.g. params_buffer_bytes() Signed-off-by: Lars-Peter Clausen Signed-off-by: Takashi Iwai --- diff --git a/include/sound/pcm_params.h b/include/sound/pcm_params.h index 2e2169e4985f..042049bab0b9 100644 --- a/include/sound/pcm_params.h +++ b/include/sound/pcm_params.h @@ -363,9 +363,7 @@ params_subformat(const struct snd_pcm_hw_params *p) static inline unsigned int params_period_bytes(const struct snd_pcm_hw_params *p) { - return (params_period_size(p) * - snd_pcm_format_physical_width(params_format(p)) * - params_channels(p)) / 8; + return hw_param_interval_c(p, SNDRV_PCM_HW_PARAM_PERIOD_BYTES)->min; } /**
