    Subject[PATCH 5.19 0985/1157] ASoC: audio-graph-card2: Add of_node_put() in fail path
    Date
    From: Liang He <windhl@126.com>

    [ Upstream commit 8ebc4dd8250fd1cb5da2869c0fe6ae3686fe41e9 ]

    In asoc_simple_parse_dai(), we should call of_node_put() for the
    reference returned by of_graph_get_port_parent() in fail path.

    Fixes: 6e5f68fe3f2d ("ASoC: add Audio Graph Card2 driver")
