[PATCH v2 4/8] Coccinelle: atomic_as_refcounter: Use type âexpressionâ for another metavariable

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Mon, 16 Jul 2018 18:00:54 +0200

The metavariable âaâ is enclosed by parentheses in two rules of
a script for the semantic patch language.
Replace its type by âexpressionâ so that the corresponding source code
search becomes more powerful.
