When I integrated CONFIG_SND_HDA_SCODEC_TAS2781_SPI and compiled the whole kernel,
it used to popup the following message for TAS2781 SPI module in first compile:
 
 Build TAS2781 HD-audio side codec support for SPI Bus (SND_HDA_SCODEC_TAS2781_SPI) [N/m/?] (NEW) 

Normally, selected m. And TAS2781 SPI module would be compiled.
