Subject: [PATCH 3/4] hwspinlock: sprd: Remove redundant PM runtime implementation
Date: Mon, 14 Oct 2019 15:07:45 +0800	[thread overview]
Message-ID: <8fb54e417ee5833e09103fd1c286c4cf2f41ce69.1571036463.git.baolin.wang@linaro.org> (raw)

In-Reply-To: <cover.1571036463.git.baolin.wang@linaro.org>

Since the hwspinlock core has changed the PM runtime to be optional, thus
remove the redundant PM runtime implementation in the Spreadtrum hwlock
driver.
