From 0731a50feba67a829b86df6dffec682c821f1152 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sun, 5 Mar 2017 23:44:35 +0200 Subject: [PATCH] block: Constify data passed by pointer to blk_name MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit blk_name() is not modifying data passed to it through pointer and it returns also a pointer to const so the argument can be made const for code safeness.
