This part still fails:

	if (edid == NULL &&
	    sdvo_priv->analog_ddc_bus &&
	    !intel_analog_is_connected(intel_output->base.dev))
		edid = drm_get_edid(&intel_output->base,
				    sdvo_priv->analog_ddc_bus);

It results in this kernel message:

i2c-adapter i2c-2: unable to read EDID block.
i915 0000:00:02.0: DVI-D-1: no EDID data
