Description: SoundWire Slave status

  These properties report the Slave status, e.g. if it
  is UNATTACHED or not, and in the latter case show the
  device_number. This status information is useful to
  detect devices exposed by platform firmware but not
  physically present on the bus, and conversely devices
  not exposed in platform firmware but enumerated.
