Subject: [PATCH RESEND 2/3] hwspinlock: sirf: Remove redundant PM runtime functions
Date: Wed, 8 Jan 2020 11:23:45 +0800 [thread overview]
Message-ID: <c921e391aa2a652d8d6ae0e4041202cec9d917e7.1578453662.git.baolin.wang7@gmail.com> (raw)
In-Reply-To: <cover.1578453662.git.baolin.wang7@gmail.com>
In-Reply-To: <cover.1578453662.git.baolin.wang7@gmail.com>
Since the hwspinlock core has changed the PM runtime to be optional, and
the SIRF hardware spinlock has no pm runtime requirement, thus remove
these redundant PM runtime functions.
