While this is good for display controller drivers, the change isn't great for 
bridge drivers. Down the road we're looking at moving connector support out of 
the bridge drivers. Adding an additional dependency to connectors in the 
bridges will make that more difficult. Ideally bridges should retrieve the 
information from their sink, regardless of whether it is a connector or 
another bridge.

Please see below for an additional comment.
