From 842a8824274de3fbbc8e230355d5c75237453bf5 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 12 Jul 2016 11:23:50 +0000 Subject: regulator: act8865: Fix missing of_node_put() in act8865_pdata_from_dt() This node pointer is returned by of_get_child_by_name() with refcount incremented in this function. of_node_put() is missing when exitting this function while invalid device type. Fix it by move of_get_child_by_name() code after device type check. Found by Coccinelle.
