From 33acb54a4379ccd3494580bdc30af1aa13ee4aab Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Thu, 25 Jun 2015 15:02:54 -0700 Subject: [PATCH] checkpatch: use $String consistently String detection where a source line with a string constant is converted can either have an X or a space. Some of the string detection regexes do not allow the space character, but there is a handy $String variable that does. Convert the remaining uses of string detection regexes to use the $String variable to reduce possible false negatives.
