   4 Subject: [PATCH] libweston/backend-drm: Re-order gbm destruction at DRM-backend tear down
   5
   6 Tearing down the drm-backend when there are no input devices, would call
   7 for the gbm device destruction before compositor shutdown. The latter
   8 would call into the renderer detroy function and assume that the
   9 EGLDisplay, which was created using the before-mentioned gbm device, is
  10 still available. This patch re-orders the gbm destruction after the
  11 compositor shutdown when no one would make use of it.
