But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC. Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary. This patch moves DAI driver .suspend/.resume to Component driver Signed-off-by: Kuninori Morimoto --- sound/soc/samsung/i2s.c | 13 +++++++------ 1 file changed, 7 insertions(+), 6 deletions(-) diff --git a/sound/soc/samsung/i2s.c b/sound/soc/samsung/i2s.c index 9722940..a57bb989 100644 --- a/sound/soc/samsung/i2s.c +++ b/sound/soc/samsung/i2s.c @@ -1024,14 +1024,14 @@ i2s_delay(struct snd_pcm_substream *substream, struct snd_soc_dai *dai) } #ifdef CONFIG_PM -static int i2s_suspend(struct snd_soc_dai *dai) +static int i2s_suspend(struct snd_soc_component *component) { - return pm_runtime_force_suspend(dai->dev); + return pm_runtime_force_suspend(component->dev); } -static int i2s_resume(struct snd_soc_dai *dai) +static int i2s_resume(struct snd_soc_component *component) { - return pm_runtime_force_resume(dai->dev); + return pm_runtime_force_resume(component->dev); } #else #define i2s_suspend NULL @@ -1140,6 +1140,9 @@ static const struct snd_soc_component_driver samsung_i2s_component = { .dapm_routes = samsung_i2s_dapm_routes, .num_dapm_routes = ARRAY_SIZE(samsung_i2s_dapm_routes), + + .suspend = i2s_suspend, + .resume = i2s_resume, }; #define SAMSUNG_I2S_FMTS (SNDRV_PCM_FMTBIT_S8 | SNDRV_PCM_FMTBIT_S16_LE | \ @@ -1171,8 +1174,6 @@ static int i2s_alloc_dais(struct samsung_i2s_priv *priv, dai_drv->probe = samsung_i2s_dai_probe; dai_drv->remove = samsung_i2s_dai_remove; - dai_drv->suspend = i2s_suspend; - dai_drv->resume = i2s_resume; dai_drv->symmetric_rates = 1; dai_drv->ops = &samsung_i2s_dai_ops;
