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.
