    Subject[PATCH 5.4 064/389] ARM: OMAP2+: display: Fix refcount leak bug
    Date
    From: Liang He <windhl@126.com>

    [ Upstream commit 50b87a32a79bca6e275918a711fb8cc55e16d739 ]

    In omapdss_init_fbdev(), of_find_node_by_name() will return a node
    pointer with refcount incremented. We should use of_node_put() when
    it is not used anymore.
