[PATCH 5/6] fbdev: s3c-fb: Make use of the helper function dev_err_probe()

From: Cai Huoqing
Date: Fri Sep 17 2021 - 00:22:59 EST


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.
