Subject: [PATCH 2/3] Input: elants_i2c - Make use of the helper function devm_add_action_or_reset()
Date: Wed, 22 Sep 2021 20:52:10 +0800 [thread overview]
Message-ID: <20210922125212.95-2-caihuoqing@baidu.com> (raw)
In-Reply-To: <20210922125212.95-1-caihuoqing@baidu.com>
The helper function devm_add_action_or_reset() will internally
call devm_add_action(), and if devm_add_action() fails then it will
execute the action mentioned and return the error code. So
use devm_add_action_or_reset() instead of devm_add_action()
to simplify the error handling, reduce the code.
