[PATCH] coccinelle: merge twelve rules from object_id.cocci
From: Markus Elfring <hidden>
Date: 2019-11-14 12:10:45
From: Markus Elfring <redacted> Date: Thu, 14 Nov 2019 12:48:27 +0100 This script contained transformation rules for the semantic patch language which used similar code. Combine these rules by using five SmPL disjunctions so that the run time characteristics can be nicer because of common usage of a few metavariables.
