Subject: localmodconfig: Add config depends by default settings
X-Git-Tag: upstream/snapshot3+hdmi~3656^2
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=95edca5c523c4b404dd60baa0a1bea0e4c38fd72;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

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.
