From 9e0c25795b42f2d3df3c9b5378d5f6d5b84a2c9c Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Thu, 23 Feb 2017 01:03:06 +0000 Subject: [PATCH] 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.
