Do you mean, it could save you from Oops, but you still have warning ?
It seems soc-dapm::snd_soc_dapm_add_routes() failed.
Your kernel is missing widget route/path ?
Or, sound card driver has some issue ?
I have been faced this error many times.
I don't remember detail, but, if my memory was correct,
it was always card driver setup timing, or missing something, in my case.
Thank you for your help !!
Best regards
