I can feel this log is not required, but still it's upto you.

This message is misleading like "system is unable to get the HDMI 
connector event though there is one connected". Please update this log 
something like "NO HDMI connector found".

Please add a period '.' at the end of every sentence.

---------------------------------^
Adding the connector name to the log is more user friendly.
igt_info("%s-%d: <your msg>\n", connector_type, connector_type_id);
