The elements of struct drm_writeback_connector are
struct drm_writeback_connector {
Struct drm_connector base;
Struct drm_encoder encoder;
Similarly the elements of intel_encoder and intel_connector are
struct intel_encoder {
Struct drm_encoder base;
Struct intel_connector {
Struct drm_connector base;
The function drm_writeback_connector_init() will initialize the drm_connector
and drm_encoder and attach them as well.
Since the drm_connector/encoder are both struct in drm_writeback_connector and
intel_connector/encoder, one of them should be a pointer, else both will be
pointing to 2 separate 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.

Sure we will add this in Cc in the next series of patches
