From b14caecdbe7730bf82c8510f1ba52e00273e15c4 Mon Sep 17 00:00:00 2001 From: Andres Salomon Date: Wed, 11 Feb 2009 13:04:22 -0800 Subject: gxfb: properly alloc cmap and plug cmap leak We weren't properly allocating the cmap for depths greater than 8bpp, which caused pain for things like DirectFB. Also, we never freed the cmap memory upon module unload..
