From 01298ca2c839965f54d6d6a7b8ac00fe77190116 Mon Sep 17 00:00:00 2001 From: Andreas Fritiofson Date: Sat, 28 Sep 2013 23:01:07 +0200 Subject: [PATCH] binarybuffer: Remove unnecessary cast and fix hidden "bug" Because of the cast, the const decoration on the parameter provided no guarantee against modification since it was silently discarded.
