Maybe, can you add a prompt which is only displayed
if COMPILE_TEST is enabled?



For example,

config SND_SOC_L3
        tristate "some prompt" if COMPILE_TEST




In normal use-cases, this CONFIG option is hidden
since we expect it to be selected by some machine options.

If COMPILE_TEST is enabled, we can toggle as you like.


If I run
 $ git grep  "if COMPILE_TEST"

I see many usages of this tip.
