Subject: [PATCH] dmaengine: imx-sdma: Remove useless null check before call of_node_put()
Date:   Thu, 21 Apr 2022 10:49:50 +0800
Message-ID: <1650509390-26877-1-git-send-email-baihaowen@meizu.com>

Precedence: bulk

No need to add null check before call of_node_put(), since the
implementation of of_node_put() has done it.
