From 6160bf97db8bc493512795b1fa49c072a703df50 Mon Sep 17 00:00:00 2001 From: Frank Binns Date: Thu, 22 Feb 2018 13:37:54 +0000 Subject: [PATCH] egl/dri2: fix segfault when display initialisation fails dri2_display_destroy() is called when platform specific display initialisation fails. However, this would typically lead to a segfault due to the dri2_egl_display vbtl not having been set up.
