[PATCH 3/6] Coccinelle: ptr_err_to_pe: Restrict the metavariable type “constant” for the usage of string literals

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Tue, 30 Sep 2025 17:28:20 +0200

Refine the metavariable type “constant” with “char[]” so that only
string literals should be found for the desired source code search.
