    Subject[PATCH 4.9 078/148] ARM: OMAP2+: Release device node after it is no longer needed.
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Guenter Roeck <linux@roeck-us.net>


    [ Upstream commit b92675d998a9fa37fe9e0e35053a95b4a23c158b ]

    The device node returned by of_find_node_by_name() needs to be released
    after it is no longer needed to avoid a device node leak.
