Subject: [PATCH 5/5] Coccinelle: put_device: Merge two SmPL when constraints
 into one

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 13 May 2019 09:55:22 +0200

A single parameter was repeated for a function call in two SmPL
when constraints.
Combine the exclusion specifications into a disjunction for the semantic
patch language so that this argument is referenced only once there.
