Subject[PATCH v3] ASoC: samsung: wm8994 depends on mfd_wm8994
Date
Any driver that selects SND_SOC_WM8994 should also make sure that
MFD_WM8994 is set, since the codec relies on the mfd code:

sound/built-in.o: In function `wm8994_read':
last.c:(.text+0x20160): undefined reference to `wm8994_reg_read'
sound/built-in.o: In function `wm8994_write':
last.c:(.text+0x20e68): undefined reference to `wm8994_reg_write'

This solves the problem by selecting the MFD driver directly
and adding extra 'depends on' statements to make sure that we
respect the dependencies of that driver.

I'm still confused, I thought you had NAKed the patch that selects the
core because it ignores the dependencies. Here comes another variant,
this time for your branch, and selecting the MFD driver directly while
respecting its dependencies.

No, certainly not. This patch by itself helps nobody, the only reason
for doing it is to make randconfig work and that requires lots of
other patches.
