From 95330473636e5e4546f94874c957c3be66bb2140 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Fri, 24 Feb 2017 15:01:43 -0800 Subject: checkpatch: remove false unbalanced braces warning Lines containing "} else {" should not be detected as unbalanced braces. But the second check can be reduced to ".+else\s*{" and it therefore never checked if the beginning of a line contains any other character (like the relevant "}"). This check would also return true for "} else {" and create warnings like CHECK: Unbalanced braces around else statement #391: FILE: ./net/batman-adv/tvlv.c:391: + } else { The check can be changed to check the whole line for the missing "}" to avoid this false positive.
