Given:

config A
tristate "a"

config B
tristate "b"
depends on A

config C
bool "c"
require B

CONFIG_A=m

Will C be visible?

The underlying problem is that we use bool for two different cases:
- non-modular driver (answer would be "no")
- enable feature in driver (answer would be "depends on the value of D")
