From cd9978f1d3dbb9596a7ab9c652cb0d9b355489b5 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 29 Dec 2014 19:41:43 +0100 Subject: ALSA: pcm: Simplify params_period_bytes() The hw_params struct has a parameter that contains the period size in bytes. 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 --- include/sound/pcm_params.h | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) (limited to 'include/sound/pcm_params.h') 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; } /** -- cgit v1.2.3-59-g8ed1b
