This is due to the inheritance limitation in C. This series intends to solve it by moving the drm_writeback_connector within the drm_connector and remove the drm_connector base which was in drm_writeback_connector. This is done in union with hdmi connector within drm_connector to save memory and since drm_connector cannot be both hdmi and writeback it serves is well. A RFC version was floated and discussion had taken place at [1] which kicked of this more cleaner series. We do all other required modifications that come with these changes along with addition of new function which returns the drm_connector when drm_writeback_connector is present. This series also contains some writeback API cleanups as a consequence of writeback connector moving into drm_connector All drivers will be expected to allocate the drm_connector. This discussion was tiggered from [2] and sits on top of Dmitry's series see [3].
