From f17dba4fc0496eb0daf018074fccebdc85993c75 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Mon, 13 Oct 2014 15:51:51 -0700 Subject: checkpatch: add --strict test for concatenated string elements Using a space between concatenated string elements is easier for a human to read. ie: "String"FOO"bar" is easier to read as: "String" FOO "bar" So suggest this style with a --strict command line option.
