Subject: [PATCH] phy: rockchip-inno-usb2: Make use of the helper function devm_add_action_or_reset()
Date: Wed, 22 Sep 2021 21:00:23 +0800 [thread overview]
Message-ID: <20210922130024.745-1-caihuoqing@baidu.com> (raw)
The helper function devm_add_action_or_reset() will internally
call devm_add_action(), and gif 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.
