From 398539dd69341f8e3b87b8fea9355c7edfb6d99a Mon Sep 17 00:00:00 2001 From: Yangtao Li Date: Thu, 27 Dec 2018 12:45:51 -0500 Subject: csky: Don't leak device tree node reference of_find_node_by_type() acquires a reference to the node returned by it and that reference needs to be dropped by its caller. setup_smp() doesn't do that, so fix it by converting to for_each_of_cpu_node().
