2525  * FUNCTION   : mm_camera_muxer_unmap_buf_ops
2526  *
2527  * DESCRIPTION: ops for unmapping stream buffer via domain socket to server.
2528  *              This function will be passed to upper layer as part of ops table
2529  *              to be used by upper layer when allocating stream buffers and unmapping
2530  *              buffers to server via domain socket.
2531  *
2532  * PARAMETERS :
2533  *   @frame_idx    : index of buffer within the stream buffers, only valid if
2534  *                   buf_type is CAM_MAPPING_BUF_TYPE_STREAM_BUF or
2535  *                   CAM_MAPPING_BUF_TYPE_OFFLINE_INPUT_BUF
2536  *   @plane_idx    : plane index. If all planes share the same fd,
2537  *                   plane_idx = -1; otherwise, plean_idx is the
2538  *                   index to plane (0..num_of_planes)
2539  *   @userdata     : user data ptr (stream object)
2540  *
2541  * RETURN     : int32_t type of status
2542  *              0  -- success
2543  *              -1 -- failure
