Subject: [PATCH 6/6] Coccinelle: atomic_as_refcounter: Use format strings
 directly in SmPL rules

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 2 Jul 2018 19:46:45 +0200

Format strings were always assigned to the Python variable “msg”
before they were used in four rules of a script for the semantic
patch language.
Delete these extra variables so that the specified string objects
are directly used for the desired data output.
