Subject: [PATCH 1/2] thermal: imx: Use dev_err_probe() to simplify error handling
Date: Tue, 11 Aug 2020 10:58:34 +0800	[thread overview]
Message-ID: <1597114715-1073-1-git-send-email-Anson.Huang@nxp.com> (raw)

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