    Subject[PATCH 4.9 327/329] regulator: of: Add a missing of_node_put() in an error handling path of of_regulator_match()
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

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

    From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>

    [ Upstream commit 30966861a7a2051457be8c49466887d78cc47e97 ]

    If an unlikely failure in 'of_get_regulator_init_data()' occurs, we must
    release the reference on the current 'child' node before returning.
