This change would break things severely. This won't allow to build it
as a module any longer.
Isn't this fixed already?
See the patch 'ASoC: SOF: core: fix undefined nocodec reference' and
Takashi's follow-up to fix the unused variable warning.
Possibly the problem still persists although I haven't seen through my
local build tests with randconfig. You can set SND_SOC_SOF=y and
SND_SOC_NOCODEC=m, i.e. built-in sof-core while nocodec is a module.
YueHiabing, can you share the config and SHA1 so that we can double check?
If the problem persists, we can do something like
config SND_SOF_NOCODEC_SUPPORT
bool "SOF nocodec mode support"
config SND_SOF_NOCODEC
tristate
confir SND_SOC_SOF
tristate
select SND_SOF_NOCODEC if SND_SOF_NOCODEC_SUPPORT
that way you propagate the required dependencies
Takashi
A better fix would be to somehow restrict the SND_SOC_SOF_NOCODEC to
align with SND_SOC_SOF, i.e. disallow SND_SOC_SOF=y &&
SND_SOC_SOF_NOCODEC=m. Because of the complex mix of select and
depends-on in SOF, I'm afraid that it's not that trivial, though.
There might be something I overlooked, hopefully...
An easier alternative would be to replace
IS_ENABLED(CONFIG_SND_SOC_SOF_NOCODEC) with
IS_REACHABLE(CONFIG_SND_SOC_SOF_NOCODEC). This assures the condition
at the build time, although the error at probe might be a surprising
to some users that don't know this hidden dependency.
thanks,
Takashi

This adds support for a dummy/nocodec machine driver fallback
option if no known codec is detected. This is typically only
