Subject: [PATCH 3.16 237/245] [media] media-devnode: just return 0 instead
 of using a var
In-Reply-To: <lsq.1587683027.831233700@decadent.org.uk>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

3.16.83-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Mauro Carvalho Chehab <m.chehab@samsung.com>

commit 8b37c6455fc8f43e0e95db2847284e618db6a4f8 upstream.

Instead of allocating a var to store 0 and just return it,
change the code to return 0 directly.
