Subject: checkpatch: warn only on "space before semicolon" at end of line
X-Git-Tag: next-20140106~2^2~90
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d000be05e3c7ef47f49a0991402837d67b042d7d;p=karo-tx-linux.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.
