Subject: [PATCH] localmodconfig: Add config depends by default settings
Currently localmodconfig will miss dependencies from the default option.
For example:
config FOO
default y if BAR || ZOO
If FOO is needed for a module and is set to '=m', and so are BAR or ZOO,
localmodconfig will not see that BOO or ZOO are also needed for the foo
module, and will incorrectly disable them.
