From 3631cb83ddb13dee08923103e837130069a9944b Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Sun, 21 Aug 2011 06:10:01 +0000 Subject: [PATCH] powerpc/powermac: Add missing of_node_put np is initialized to the result of calling a function that calls of_node_get, so of_node_put should be called before the pointer is dropped.
