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/atmel/atmel_ssc_dai.c | 18 ++++++++---------- 1 file changed, 8 insertions(+), 10 deletions(-) diff --git a/sound/soc/atmel/atmel_ssc_dai.c b/sound/soc/atmel/atmel_ssc_dai.c index ca60339..1073f46 100644 --- a/sound/soc/atmel/atmel_ssc_dai.c +++ b/sound/soc/atmel/atmel_ssc_dai.c @@ -760,12 +760,12 @@ static int atmel_ssc_trigger(struct snd_pcm_substream *substream, } #ifdef CONFIG_PM -static int atmel_ssc_suspend(struct snd_soc_dai *cpu_dai) +static int atmel_ssc_suspend(struct snd_soc_component *component) { struct atmel_ssc_info *ssc_p; - struct platform_device *pdev = to_platform_device(cpu_dai->dev); + struct platform_device *pdev = to_platform_device(component->dev); - if (!cpu_dai->active) + if (!component->active) return 0; ssc_p = &ssc_info[pdev->id]; @@ -787,15 +787,13 @@ static int atmel_ssc_suspend(struct snd_soc_dai *cpu_dai) return 0; } - - -static int atmel_ssc_resume(struct snd_soc_dai *cpu_dai) +static int atmel_ssc_resume(struct snd_soc_component *component) { struct atmel_ssc_info *ssc_p; - struct platform_device *pdev = to_platform_device(cpu_dai->dev); + struct platform_device *pdev = to_platform_device(component->dev); u32 cr; - if (!cpu_dai->active) + if (!component->active) return 0; ssc_p = &ssc_info[pdev->id]; @@ -839,8 +837,6 @@ static const struct snd_soc_dai_ops atmel_ssc_dai_ops = { }; static struct snd_soc_dai_driver atmel_ssc_dai = { - .suspend = atmel_ssc_suspend, - .resume = atmel_ssc_resume, .playback = { .channels_min = 1, .channels_max = 2, @@ -860,6 +856,8 @@ static struct snd_soc_dai_driver atmel_ssc_dai = { static const struct snd_soc_component_driver atmel_ssc_component = { .name = "atmel-ssc", + .suspend = atmel_ssc_suspend, + .resume = atmel_ssc_resume, }; static int asoc_ssc_init(struct device *dev)
