Subject: [PATCH] i2c: imx: Use dev_err_probe() to simplify error handling
Date:   Wed, 12 Aug 2020 11:45:54 +0800
Message-Id: <1597203954-1803-1-git-send-email-Anson.Huang@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

dev_err_probe() can reduce code size, uniform error handling and record the
defer probe reason etc., use it to simplify the code.
