From d171c7b3ba346c4d0bd6494f45ebf0be3c3cc5fb Mon Sep 17 00:00:00 2001

Subject: [PATCH] libweston/backend-drm: Re-order gbm destruction at
DRM-backend tear down
Tearing down the drm-backend when there are no input devices, would call
for the gbm device destruction before compositor shutdown. The latter
would call into the renderer detroy function and assume that the
EGLDisplay, which was created using the before-mentioned gbm device, is
still available. This patch re-orders the gbm destruction after the
compositor shutdown when no one would make use of it.
Fixes: #314
