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.
Can I confirm it ?
In local email, I asked printing component name list.
Can you please replace it to below ?
I think disappear component is "snd_dmaengine_pcm".
If so, above my patch is the bug.
