Subject: checkpatch: reduce false positive rate of "complex macros"
X-Git-Tag: upstream/snapshot3+hdmi~4788^2~229
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3cc4b1c3f0d283f4bb8d49059bd6df8e7af7558b;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

checkpatch: reduce false positive rate of "complex macros"

Allow "#define foo struct.member" without bleating a warning.

This also allows "#define foo bar.baz->qux" and so on.
