Yeah looking at this again, do we really need this patch? Couldn't we instead change patch 1 to first allocate the fake platform device, then pass that to drm_dev_alloc (instead of NULL like we do now)?
That way no resurrection of drm_device.platform_dev is needed (and I'd really like this zombie to stay dead on 2nd thought).
