Hi Marek, again
Thank you for your test. And so sorry to bother you. I will fixup this issue.
I have no idea so far, but one capability is that if your system used / based dummy platform, and if your CPU driver didn't use/have snd_soc_set_runtime_hwparams() / snd_pcm_lib_ioctl, it might be happen, but this patch seems not related to it...
Reverting this patch fixes the issue, so it is definitely related somehow.
Ahh... OK now I think I could understand your issue. Your CPU is using devm_snd_dmaengine_pcm_register() with same *dev. In such case, indeed this patch breaks sound card.
I'm now negotiating to Mark to reverting issue patches. But, as alternative idea, I think below patch can solve this issue. Can you please test it ?

Yes, the above change fixes the issue on Samsung Snow, Peach-Pit and Peach-Pi Chromebooks, but causes regression on the other boards, for example here is the log from Odroid U3:
