Since the drm_connector/encoder are both struct in drm_writeback_connector and intel_connector/encoder, we need one of them to be a pointer so we can reference them or else we will be pointing to 2 seprate instances. Usually the struct defined in drm framework pointing to any struct will be pointer and allocating them and initialization will be done with the users. Like struct drm_connector and drm_encoder are part of drm framework and the users of these such as i915 have included them in their struct intel_connector and intel_encoder. Likewise struct drm_writeback_connector is a special connector and hence is not a user of drm_connector and hence this should be pointers. Adding drm_writeback_connector to drm_connector so that writeback_connector can be fetched from drm_connector as the previous container_of method won't work due to change in the feilds of drm_connector and drm_encoder in drm_writeback_connector. Note:The corresponding ripple effect due to the above changes namely in two drivers as I can see it komeda and vkms have been dealt with in the upcoming patches of this series.
