From f0bd716425d1514b62565f9a65397cd1cb2ffb3a Mon Sep 17 00:00:00 2001

Subject: sna: Sanitize output->crtc before falling back oto xf86InitialConfiguration
During initialisation, we stash the currently attached CRTC id in
output->crtc. This is fine as ordinarily we would not dereference
output->crtc until after it had been assigned a real CRTC. However,
commit 6fda305e2f2f991b39d09e67d0b17c8c3d50f9a4
Author: Chris Wilson <chris@chris-wilson.co.uk>
Date: Wed Oct 9 15:59:42 2013 +0100
sna: Append the current mode to the output list if not found
introduces such an early dereference and causes a crash if we fail to
probe the KMS configuration (usually due to a user override).
