+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
