From ece9659f16e369d344fe4325d87fab3bb50d1fe2 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 6 Aug 2014 16:11:29 -0700 Subject: [PATCH] checkpatch: warn on missing spaces in broken up quoted Checkpatch already complains when people break up quoted strings but it's still pretty common. One mistake that people often make is they leave out the space character between the two strings. This check adds around 450 new warnings and has a low rate of false positives.
