Subject: [PATCH v2 -next] misc: ocxl: use DEFINE_MUTEX() for mutex lock
Date: Thu, 24 Dec 2020 21:24:46 +0800 [thread overview]
Message-ID: <20201224132446.31286-1-zhengyongjun3@huawei.com> (raw)
mutex lock can be initialized automatically with DEFINE_MUTEX()
rather than explicitly calling mutex_init().
