{"TXNW2781", },This seems wrong. The ID here is correct from ACPI specification perspective. Can you elaborate why you think it's "non-conforming _HID"?
Just put into middle of array, should no effective to functions. Ok, I will change it's position in next patch.

Actually these 'objs' has to be 'y', can you fix it in the prerequisite patch?
Do you mean set CONFIG_SND_HDA_SCODEC_TAS2781_SPI=y in .config? It's m now.
Also wondering why fwlib is only a requirement for SPI. How does I²C work?
Because in I2C mode, one probed device driver will support all devices, firmware binary is only one file, include all of devices. But in SPI mode, multi driver probed, so we use single firmware binary for every spi device.
