Subject: [PATCH 02/10] nvmem: sc27xx: Change to use devm_hwspin_lock_request_specific() to request one hwlock
Date: Tue, 29 Oct 2019 11:42:32 +0000	[thread overview]
Message-ID: <20191029114240.14905-3-srinivas.kandagatla@linaro.org> (raw)
In-Reply-To: <20191029114240.14905-1-srinivas.kandagatla@linaro.org>

From: Baolin Wang <baolin.wang@linaro.org>

Change to use devm_hwspin_lock_request_specific() to help to simplify the
cleanup code for drivers requesting one hwlock. Thus we can remove the
redundant sc27xx_efuse_remove() and platform_set_drvdata().
