The config that failed for me had CONFIG_SND_SOC_MT6359_ACCDET.

I had not seen that patch, but with that applied, my patch needs to
be revised as well. If the idea is that CONFIG_SND_SOC_MT8188_MT6359
can work correctly without CONFIG_SND_SOC_MT6359_ACCDET, it should be

      depends on SND_SOC_MT6359_ACCDET || !SND_SOC_MT6359_ACCDET

in order to force SND_SOC_MT8188_MT6359=m if the ACCDET portion
is in a loadable module.

If SND_SOC_MT8188_MT6359 requires SND_SOC_MT6359_ACCDET to work
correctly, then my original patch is still needed and yours
should be reverted.
