+Subject: [PATCH] gl-renderer: Avoid double-free on init failure
+
+If gl-renderer fails its initialisation, we return to compositor
+teardown, which will try to free the renderer if ec->renderer was set.
+This is unfortunate when we've already torn it down whilst failing
+gl-renderer init, so just clear the renderer member so we don't try to
+tear down twice.

+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
