[alsa-devel] [PATCH 0/3] ASoC: remove snd_soc_pcm_set/get_drvdata()

[Kuninori Morimoto]

Hi Mark

snd_soc_pcm_set_drvdata() will set driver data to rtd->dev,
but driver data of rtd->dev is already used as "rtd" on
soc_post_component_init().

	static int soc_post_component_init(xxx)
	{
		...
		dev_set_drvdata(rtd->dev, rtd);
		...
	}

But, ASoC has snd_soc_pcm_set/get_drvdata() to set rtd->dev.
It will overwrite existing data and will break system.
This patch tries to solve this issue.
Intel haswell and qcom is using these functions.

** Note **

I don't have these boards, thus, I did compile test only.

Kuninori Morimoto (3):
      ASoC: sst-haswell-pcm: don't use snd_soc_pcm_set_drvdata()
      ASoC: lpass-platform: don't use snd_soc_pcm_set_drvdata()
      ASoC: remove snd_soc_pcm_set/get_drvdata()
