True, it's not the same build coverage need as subsystem/interface dependencies, but still:

1. Drivers can be built independently, so why not?
2. There is no drawback in allowing to building them independently

(compile test). 3. The parent MFD device could also depend on something (RK817 and MFD_LOCHNAGAR depends on I2C and OF; CPCAP on SPI), so it's not always the case of just enabling parent. IOW, you can compile test codecs without I2C and SPI which is valuable itself.

I find the last reason actually quite valid and applicable here. If you wish I can add it to the commit msg.

You've already found one case where there's a dependency being pulled in by the parent, I suspect there's more. There's a tradeoff between getting coverage and having to deal with the noise from randconfigs.
