For what it's worth, that stream of WARNINGs was reported for v3.19-rc1
in http://lkml.kernel.org/r/20150131211609.GA3710@yulia-desktop .

Commit f9b61ff6bce9 ("drm/i915: Push vblank enable/disable past
encoder->enable/disable") silenced it again in v4.0-rc1. I guess that
commit will end up in v3.19-stable in due time.
