[PATCH v2 08/26] media: v4l2-async: shut up an unitialized symbol warning

[Mauro Carvalho Chehab]

Smatch reports this warning:
        drivers/media/v4l2-core/v4l2-async.c:597 v4l2_async_register_subdev() 
error: uninitialized symbol 'ret'.

However, there's nothing wrong there. So, just shut up the
warning.
