From c92f5dd2c42fa61e0ef810fad4584b184ea2d50e Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Sun, 27 Jan 2013 21:16:56 +0800 Subject: regulator: Add missing of_node_put() of_find_node_by_name() returns a node pointer with refcount incremented, use of_node_put() on it when done. of_find_node_by_name() will call of_node_put() against from parameter, thus we also need to call of_node_get(from) before calling of_find_node_by_name().
