From: Laurent Pinchart <laurent.pinch...@ideasonboard.com>
To prepare for the introduction of video_device_state as second argument
of the v4l2_ioctl_ops handler, access the v4l2_fh from
file->private_data instead of using void *priv.
The file->private_data is initialized to point to the v4l2_fh
by the usage of v4l2_fh_init() in the v4l2_file_operations.open()
handler.
While at it remove the only left user of fh_to_ctx() and remove
the macro completely.
