Subject: [PATCH 1/2] hwspinlock: qcom: Remove redundant PM runtime functions
Date: Wed,  4 Dec 2019 17:21:56 +0800
Message-ID: <c75efc82fa27f191e53e8938045ce954745a4052.1575450802.git.baolin.wang7@gmail.com> (raw)
In-Reply-To: <cover.1575450802.git.baolin.wang7@gmail.com>
In-Reply-To: <cover.1575450802.git.baolin.wang7@gmail.com>

Since the hwspinlock core has changed the PM runtime to be optional, and
the Qualcomm hardware spinlock has no pm runtime requirement, thus remove
these redundant PM runtime functions.
