All CONFIG_SND_SOC_* symbols above are tristate and have dependencies
on the modular symbols.

However, the "imply" statements in SND_SOC_ALL_CODECS force all of them
builtin, despite their dependencies being modular.

So while "imply" is meant to be a softer form of "select", obeying target
dependencies, it does not seem to obey modular tristate dependencies?

Or am I missing something?
Thanks!

I quickly checked the Kconfig code.

Surprisingly or not, 'imply' does not
obey 'depends on'.

I do not know if it is a bug, or intended behavior
but at least the current code works so.
(I am guessing this is a bug...)

I checked Documentation/kbuild/kconfig-language.rst
Unfortunately, this case is not documented.

I attached a patch, which changes the 'imply' to
follow the restriction of 'depends on',
but I need to take a closer look at this.
