Thanks for the report. This looks like a valid issue but I don't think 
the fix is in the right place, we moved all Intel-specific stuff to 
sound/soc/sof/Intel.

In addition I don't get how this can happen in the first place, we have
this statement

config SND_SOC_SOF_INTEL_PCI
	def_tristate SND_SOC_SOF_PCI

Can you share the config that's broken? Thanks!
