Subject: [PATCH -next] s390/ap: remove unnecessary spin_lock_init()
Date: Wed, 16 Sep 2020 14:21:30 +0800 [thread overview]
Message-ID: <20200916062130.190910-1-miaoqinglang@huawei.com> (raw)
The spinlock ap_poll_timer_lock is initialized statically. It is
unnecessary to initialize by spin_lock_init().
