From 9d773f103b8953614e4ac28d3974719695580dcf Mon Sep 17 00:00:00 2001 From: Cai Huoqing Date: Fri, 17 Sep 2021 12:24:11 +0800 Subject: [PATCH] video: fbdev: omapfb: lcd_ams_delta: Make use of the helper function dev_err_probe() When possible use dev_err_probe help to properly deal with the PROBE_DEFER error, the benefit is that DEFER issue will be logged in the devices_deferred debugfs file. Using dev_err_probe() can reduce code size, and the error value gets printed.
