From 0633094ec7ffd63f3f014e551570aaab2db4690c Mon Sep 17 00:00:00 2001 From: Dwaipayan Ray Date: Tue, 15 Dec 2020 20:45:02 -0800 Subject: [PATCH] checkpatch: fix unescaped left brace [ Upstream commit 03f4935135b9efeb780b970ba023c201f81cf4e6 ] There is an unescaped left brace in a regex in OPEN_BRACE check. This throws a runtime error when checkpatch is run with --fix flag and the OPEN_BRACE check is executed. Fix it by escaping the left brace.
