[PATCH v3 50/76] media: rockhip: rga: Access v4l2_fh from file

[Laurent Pinchart]

From: Jacopo Mondi <jacopo.mondi at ideasonboard.com>

The v4l2_fh associated with an open file handle is now guaranteed
to be available in file->private_data, initialised by v4l2_fh_add().

Access the v4l2_fh, and from there the driver-specific structure,
from the file * in all ioctl handlers.
