[PATCH 4.4 264/268] regulator: of: Add a missing of_node_put() in an error handling path of of_regulator_match()

[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

From: Christophe JAILLET <christophe.jail...@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.
