   5 Subject: [PATCH] gl-renderer: Avoid double-free on init failure
   6
   7 If gl-renderer fails its initialisation, we return to compositor
   8 teardown, which will try to free the renderer if ec->renderer was set.
   9 This is unfortunate when we've already torn it down whilst failing
  10 gl-renderer init, so just clear the renderer member so we don't try to
  11 tear down twice.
