I was actually thinking of floating a new patch series with both encoder and 
connector pointer changes but with a change in initialization functions wherein
we allocate a connector and encoder incase the driver doesn’t have its own this
should minimize the effect on other drivers already using current drm writeback 
framework and also allow i915 to create its own connector.
We can work on Laurent's suggestion but that would first require the initial RFC
patches and then a rework from both of our drivers side to see if they gel well 
with our current code which will take a considerable amount of time. We can for
now however float the patch series up which minimally affects the current drivers
and also allows i915 and msm to move forward with its writeback implementation
off course with a proper documentation stating new drivers shouldn't try to make
their own connectors and encoders and that drm_writeback will do that for them.
Once that's done and merged we can work with Laurent on his proposal to improve 
the drm writeback framework so that this issue can be side stepped entirely in future.
For now I would like to keep the encoder and connector pointer changes together.
