Both of the function uses drm_connector_init and drm_encoder_init, but there is no way to properly clean those structure from outside. By using drm managed variants, we can ensure that the writeback connector is properly cleaned. This patch introduce drmm_writeback_connector_init, an helper to initialize a writeback connector using drm managed helpers. This function allows the caller to use its own encoder.
