  27  * parameter).

  30  * qom path as "/peripheral-anon/name". This name is not set as the id
  31  * of @dev.
  32  *
  33  * Upon success, it returns the id/name (generated or provided). The
  34  * returned string is owned by the corresponding child property and must
  35  * not be freed by the caller.
