    Subject[PATCH 4.19 105/639] clk: samsung: exynos4: fix refcount leak in exynos4_get_xom()
    Date
    From: Yangtao Li <tiny.windzz@gmail.com>

    [ Upstream commit cee82eb9532090cd1dc953e845d71f9b1445c84e ]

    The of_find_compatible_node() returns a node pointer with refcount
    incremented, but there is the lack of use of the of_node_put() when
    done. Add the missing of_node_put() to release the refcount.
