Hi Takashi,

You are right in that but the point is that user cannot select this driver

+config SND_SOC_INTEL_HDA_SKYLAKE
+       tristate
+       select SND_SOC_HDA_CORE
+       help
+         Say Y here to include support for ASoC Intel "High Definition
+         Audio" (Skylake) and its compatible devices.

So unless someone selects this symbol (machine driver) it wont be built for
anyone (expect you and me to test :D ) and wont conflict.
Or did I miss something ?

Also anyway I will add the flag in this driver as follow on to disable
registering this device so that users don't see this device getting
registered, unless we have complete story merged.

Thanks
