From b41f36bde778e6b11129f51de423b7c3aece26b4 Mon Sep 17 00:00:00 2001 From: Paulo Alcantara Date: Fri, 17 Aug 2012 14:08:10 -0300 Subject: [PATCH] egl_dri2: Fix segmentation fault The segmentation fault occurs when DRI2 is not loaded up and dri2_setup_screen() function deferences dri2_dpy->dri2 (since it's NULL at this point). This patch fixes the segmentation fault by checking if dri2 pointer is not NULL before deferencing it.
