Thats another case.
What is described is following simple situation:
config FOO
bool "Modules"
option modules
config A
tristate "a"
config B
tristate "b"
depends on A
config C
tristate "c"
depends on B
depends on A = y || A = B
C uses a symbol defined by A - let us name it foo().
If C is build-in and A is a module =>
link error - unable to resolve foo.
So we say:
if A is buildin C may be built-in or module.
if A is a module C may not be built-in.
This is what this hint describes.
I would certainly love to see some of the other typical cases
described too.
We need a description that covers the LED case. And I think
you would be the best to come up with a description considering
the time you have spent investigating it.
Could you try to come up with either a suggested wording
or a patch?
Thanks,
Sam
