Description:
stm_source device linkage to stm device, where its tracing data
is directed. Reads return an existing connection or "<none>" if
this stm_source is not connected to any stm device yet.
Write an existing (registered) stm device's name here to
connect that device. If a device is already connected to this
stm_source, it will first be disconnected.
