Subject: [PATCH] drm/sun4i: dw-hdmi: Make use of the helper function dev_err_probe()
Date: Thu, 16 Sep 2021 18:56:32 +0800 [thread overview]
Message-ID: <20210916105633.12162-1-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.
And using dev_err_probe() can reduce code size, the error value
gets printed.
