[PATCH 3.16 237/245] [media] media-devnode: just return 0 instead of using a var

[Ben Hutchings]

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

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

From: Mauro Carvalho Chehab <m.chehab@xxxxxxxxxxx>

commit 8b37c6455fc8f43e0e95db2847284e618db6a4f8 upstream.

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