The difference between the i915 driver and the nouveau (and amdgpu) driver is
that in the i915 driver the drm_dp_cec_set_edid/unset_edid/irq functions are
called from code that is exclusively for DisplayPort connectors.
For nouveau/amdgpu they are called from code that is shared between DisplayPort
and HDMI, so aux->transfer may be NULL.
Rather than either testing for the connector type or for a non-NULL aux-...
