However,\na successful open replaces file->f_op with the output driver file\noperations before returning, so close runs the output driver release\ncallback instead.\n\nFor MSC outputs, close runs intel_th_msc_release(), which only removes\nthe per-file iterator and does not drop the device reference taken by\nintel_th_output_open().
