Is this correct? You are adding a dead "code", isn't it?
What's mean "dead code"? After add CONFIG_SND_HDA_SCODEC_TAS2781_SPI=m in my config file, the whole patch code has worked.
Is that file already in the repository? If not, I don't see it in this patch either --> dead code.
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.
The above is a dead code if this SPI driver is not yet in the kernel. Is it? What is the path to it in the current kernel source tree?
