Subject: [PATCH] pwm: imx27: Eliminate error message for defer probe
Date:   Mon, 30 Dec 2019 11:02:40 +0800
Message-Id: <1577674960-12011-1-git-send-email-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

For defer probe error, no need to output error message which
will cause confusion.
