I am bisecting down to 5 asoc related commits now, and currently building "ASoC: pcm_dmaengine: Extra snd_dmaengine_pcm_refine_runtime_hwpararms". The breakage is between "...remove snd_soc_soc_rtdcom_del_all()" and "Merge branch asoc-5.4 into asoc-5.5". It takes about an hour to do a clean build.
I think it is either that hwparams commit or the next one, "use different sequence..."?
I shall be able to tell you for sure in a few more hours / next day.
Any thoughts on those two?
