Subject: [PATCH] media: siano: use DEFINE_MUTEX() for mutex lock
Message-ID: <20210405205219.GA687366@LEGION>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

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