Subject: [PATCH v2 -next] staging: most: net: use DEFINE_MUTEX() for mutex lock
Date: Thu, 24 Dec 2020 21:25:19 +0800	[thread overview]
Message-ID: <20201224132519.31504-1-zhengyongjun3@huawei.com> (raw)

mutex lock can be initialized automatically with DEFINE_MUTEX()
rather than explicitly calling mutex_init().
