Subject: [PATCH 3/3] hwspinlock: u8500_hsem: Use devm_hwspin_lock_register() to register hwlock controller
Date: Fri, 27 Sep 2019 16:27:43 +0800	[thread overview]
Message-ID: <a6b18f17b995bceaf2fc0129866301dd8f46bee4.1569572448.git.baolin.wang@linaro.org> (raw)
In-Reply-To: <cover.1569572448.git.baolin.wang@linaro.org>
In-Reply-To: <cover.1569572448.git.baolin.wang@linaro.org>

Use devm_hwspin_lock_register() to register the hwlock controller instead of
unregistering the hwlock controller explicitly when removing the device.
