Subject: [PATCH 1/3] ASoC: sst-haswell-pcm: don't use snd_soc_pcm_set_drvdata()


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);
		...
	}

To remove confusion, snd_soc_pcm_set/get_drvdata() should be
removed soon. This patch is for it.

intel/haswell/sst-haswell-pcm.c is using snd_soc_pcm_set(),
but no one use it on this driver. Let's remove it.

I did compile test only.
