Unfortunately it doesn't work like that. As the tristate has no prompt
specified, the user will never be asked about this.
You should use something like below:

--- a/drivers/mux/Kconfig
+++ b/drivers/mux/Kconfig
@@ -4,10 +4,8 @@
 #

 config MULTIPLEXER
-       tristate
+       tristate "Generic Multiplexer Support" if COMPILE_TEST
        help
-         Generic Multiplexer Support.
-
          This framework is designed to abstract multiplexer handling for
          devices via various GPIO-, MMIO/Regmap or specific multiplexer
          controller chips.

Sorry for not noticing before.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
