 Below is a short description of the v4l2_fh functions used:
 
-int v4l2_fh_init(struct v4l2_fh *fh, struct video_device *vdev)
+void v4l2_fh_init(struct v4l2_fh *fh, struct video_device *vdev)
 
   Initialise the file handle. This *MUST* be performed in the driver's
   v4l2_file_operations->open() handler.
