Subject: [PATCH -next] tty: serial: Use DEFINE_SPINLOCK() for spinlock
Date: Wed, 23 Dec 2020 22:14:38 +0800 [thread overview]
Message-ID: <20201223141438.889-1-zhengyongjun3@huawei.com> (raw)
spinlock can be initialized automatically with DEFINE_SPINLOCK()
rather than explicitly calling spin_lock_init().
