[Intel-gfx] [PATCH 2/5] drm/i915: hdmi: add CEC notifier to intel_hdmi
This patchs adds the cec_notifier feature to the intel_hdmi part
of the i915 DRM driver. It uses the HDMI DRM connector name to differentiate
between each HDMI ports.
The changes will allow the i915 HDMI code to notify EDID and HPD changes
to an eventual CEC adapter.

I just figured it out, I was busy on the CEC driver and notifier, will re-spin
a v2 with this and the other small fixes you requested.

You haven't figured yet out where to place the cec_notifier_put() call?
Or did you forget?
