Hi,

This is v10 of the writeback connector series. Compared to v9 I've
reverted to the v6 way of cleaning up the writeback job in the cleanup_work()
function, where we also drop the reference to the job's framebuffer. I was
trying to come up with a reference counted implementation for the job, but
Sean Paul pointed out to Brian that it seems to be safe to free work_struct
structures in the workqueue callback, so we are going back to the original
implementation.

While doing that, I've also updated the patcheset to use the latest
drm_framebuffer_{put,get,assign} functions for managing the framebuffer
reference that the wriback job holds.

I will ask Gustavo to pull this series into drm-misc if there are no further
comments.

Best regards,
Liviu
