Subject: checkpatch: warn only on "space before semicolon" at end of line
X-Git-Tag: upstream/snapshot3+hdmi~3586^2~92
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=d2e248e7b0068b940f3ca1fc26da603536a533db;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git

checkpatch: warn only on "space before semicolon" at end of line

The "space before a non-naked semicolon" test has unwanted output when
used in "for ( ;; )" loops.

Make the test work only on end-of-line statement termination semicolons.
