Subject: [PATCH -next] fpga: Use DEFINE_SPINLOCK() for spinlock
Date: Mon, 28 Dec 2020 21:51:35 +0800	[thread overview]
Message-ID: <20201228135135.28788-1-zhengyongjun3@huawei.com> (raw)

spinlock can be initialized automatically with DEFINE_SPINLOCK()
rather than explicitly calling spin_lock_init().
