Subject: [PATCH] media: platform: remove redundant null pointer check before of_node_put
Date:   Sun, 16 Sep 2018 21:16:51 +0800
Message-ID: <1537103811-63670-1-git-send-email-zhongjiang@huawei.com>
MIME-Version: 1.0
Content-Type: text/plain
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

of_node_put has taken the null pinter check into account. So it is
safe to remove the duplicated check before of_node_put.
