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.
