Subject: [PATCH] powpc:feature: of_node_put is not needed after iterator.
Date:   Sat, 4 Aug 2018 22:25:00 +0800
Message-ID: <1533392700-24621-1-git-send-email-zhongjiang@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

for_each_node_by_name iterators only  exit normally when the loop
cursor is NULL, So there is no point to call of_node_put.
