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.


Best regards,
Krzysztof
