Reusing the Big DRM Lock just leaks, and the few things left that dev->struct_mutex protected are very well contained - it's just the linear drm_mm manager. With this armada is completely struct_mutex free! v2: Convert things properly and also take the lock in armada_gem_free_object, and remove the stale comment (Russell).
