Some drivers cannot work with the current design where the connector is embedded within the drm_writeback_connector such as intel and some drivers that can get it working end up adding a lot of checks all around the code to check if it's a writeback conenctor or not. 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. A Proposal suggested by Dmitry. We want to get an Ack from all drivers whom are affected by these changes. 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. All drivers will be expected to allocate the drm_connector. This discussion was tiggered from [1] and sits on top of Dmitry's series see [2].
