From 3314c6bdd26880e0dfbcb0cb85a1b36d185ce47c Mon Sep 17 00:00:00 2001 From: Niklas Söderlund Date: Tue, 22 Aug 2017 02:19:12 +0200 Subject: device property: preserve usecount for node passed to of_fwnode_graph_get_port_parent() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Using CONFIG_OF_DYNAMIC=y uncovered an imbalance in the usecount of the node being passed to of_fwnode_graph_get_port_parent(). Preserve the usecount by using of_get_parent() instead of of_get_next_parent() which don't decrement the usecount of the node passed to it.
