The main problem here is, though, that this commit will break the build, because you introduced a Kconfig that can be enabled, while the corresponding code for snd-hda-scodec-tas2781-spi isn't present yet. This is bad for the git-bisection. You'd need to reorganize better how the code is added piece-by-piece. thanks, Takashi
