Subject: [PATCH] regulator: of: Add a missing 'of_node_put()' in an error
 handling path of 'of_regulator_match()'

[ 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.
