I plan to discuss this topic during the brainstorming meeting.

Documentation/media-framework.txt already states that

"If other operations need to be disallowed on streaming entities (such as
changing entities configuration parameters) drivers can explictly check the
media_entity stream_count field to find out if an entity is streaming. This
operation must be done with the media_device graph_mutex held."

OK, we'll discuss the topic during the meeting and I'll work on documentation.

Everything is there. Thanks a lot.
