Subject: [PATCH 1/6] fbdev: da8xx-fb: Make use of the helper function dev_err_probe()
Date: Fri, 17 Sep 2021 12:22:07 +0800	[thread overview]
Message-ID: <20210917042213.17689-1-caihuoqing@baidu.com> (raw)

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.
