From f0ae8cbbb8b88c04b256a6895c21a056dddbbbb1 Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Mon, 10 Sep 2012 11:14:20 +1000 Subject: [PATCH] xf86: return NULL for compat output if no outputs. With outputless GPUs showing up we crash here if there are not outputs try and recover with a bit of grace.
