Subject: [PATCH] gpu: do not double put device node in zx_drm_probe
Date:   Fri, 17 Aug 2018 10:24:06 +0800
Message-ID: <1534472646-10368-1-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_available_child_of_node will get and put the node properly,
the following of_node_put will lead to the double put. So just
remove it.
