From d4281c016d84d56abd5fc19eb0e24ca7c5138e8c Mon Sep 17 00:00:00 2001 From: Cai Huoqing Date: Fri, 17 Sep 2021 10:07:41 +0800 Subject: drm/tegra: sor: 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. And using dev_err_probe() can reduce code size, the error value gets printed.
