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/cirrus/ep93xx-i2s.c | 16 ++++++++-------- 1 file changed, 8 insertions(+), 8 deletions(-) diff --git a/sound/soc/cirrus/ep93xx-i2s.c b/sound/soc/cirrus/ep93xx-i2s.c index 7d9cf67..723f4cf 100644 --- a/sound/soc/cirrus/ep93xx-i2s.c +++ b/sound/soc/cirrus/ep93xx-i2s.c @@ -364,11 +364,11 @@ static int ep93xx_i2s_set_sysclk(struct snd_soc_dai *cpu_dai, int clk_id, } #ifdef CONFIG_PM -static int ep93xx_i2s_suspend(struct snd_soc_dai *dai) +static int ep93xx_i2s_suspend(struct snd_soc_component *component) { - struct ep93xx_i2s_info *info = snd_soc_dai_get_drvdata(dai); + struct ep93xx_i2s_info *info = snd_soc_component_get_drvdata(component); - if (!dai->active) + if (!component->active) return 0; ep93xx_i2s_disable(info, SNDRV_PCM_STREAM_PLAYBACK); @@ -377,11 +377,11 @@ static int ep93xx_i2s_suspend(struct snd_soc_dai *dai) return 0; } -static int ep93xx_i2s_resume(struct snd_soc_dai *dai) +static int ep93xx_i2s_resume(struct snd_soc_component *component) { - struct ep93xx_i2s_info *info = snd_soc_dai_get_drvdata(dai); + struct ep93xx_i2s_info *info = snd_soc_component_get_drvdata(component); - if (!dai->active) + if (!component->active) return 0; ep93xx_i2s_enable(info, SNDRV_PCM_STREAM_PLAYBACK); @@ -406,8 +406,6 @@ static const struct snd_soc_dai_ops ep93xx_i2s_dai_ops = { static struct snd_soc_dai_driver ep93xx_i2s_dai = { .symmetric_rates= 1, .probe = ep93xx_i2s_dai_probe, - .suspend = ep93xx_i2s_suspend, - .resume = ep93xx_i2s_resume, .playback = { .channels_min = 2, .channels_max = 2, @@ -425,6 +423,8 @@ static struct snd_soc_dai_driver ep93xx_i2s_dai = { static const struct snd_soc_component_driver ep93xx_i2s_component = { .name = "ep93xx-i2s", + .suspend = ep93xx_i2s_suspend, + .resume = ep93xx_i2s_resume, }; static int ep93xx_i2s_probe(struct platform_device *pdev)
