- Modeset state needs mode_config->connection mutex, that covers figuring out the encoder, and reading properties (since in the atomic case those need to look at connector->state). - Don't hold any locks for stuff that's invariant (i.e. possible connectors). - Same for connector lookup and unref, those don't need any locks. - And finally the probe stuff is only protected by mode_config->mutex. While at it updated the kerneldoc for these fields in drm_connector and add docs explaining what's protected by which locks.
