Subject: [PATCH] Input: samsung-keypad - Make use of the helper function dev_err_probe()
Date: Thu, 16 Sep 2021 23:34:10 +0800 [thread overview]
Message-ID: <20210916153410.15052-1-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.
