With the introduction of output entities, managers will now connect to outputs. Use the helper op for managers named get_device. This will abstract away the information on how to get the device from an overlay manager. Using the helper function will reduce the number of pointer dereferences a user of OMAPDSS needs to do and reduce risk of a NULL dereference.
