This patch was dropped because it was withdrawn
------------------------------------------------------
From: Joe Perches <joe@xxxxxxxxxxx>
Subject: checkpatch: improve octal permission test
The function calls with octal permissions commonly span multiple lines.
The current test is line oriented and fails to find some matches.
Make the test use the $stat variable instead of the $line variable to
span multiple lines.
