Subject: [PATCH] [media] em28xx-v4l: simplify em28xx_v4l2_open() by using
 v4l2_fh_open()
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

Instead of calling

...
struct v4l2_fh *fh = kzalloc(sizeof(*fh), GFP_KERNEL);
filp->private_data = fh;
v4l2_fh_init(fh, vdev);
v4l2_fh_add(fh);
...

simply use function v4l2_fh_open() which does all of these calls for us.
