[pulseaudio-discuss] [PATCH 03/23] Remove create_node from sink and source new data

[Tanu Kaskinen]

Every sink and source that doesn't have ports should have a node. The
ports/no ports checking can be done by the core, so node backends
don't need to explicitly tell whether a node should be created or not.
