From 86f9d059c6bc548f6337f01117897a4c823cb4ee Mon Sep 17 00:00:00 2001 From: Andy Whitcroft Date: Tue, 6 Jan 2009 14:41:24 -0800 Subject: [PATCH] checkpatch: allow parentheses on return for comparisons It seems to be a common idiom to include braces on conditionals in all contexts including return.
