[PATCH] sh_veu: convert to struct v4l2_fh

[PATCH] sh_veu: convert to struct v4l2_fh

[Hans Verkuil]

This driver didn't use struct v4l2_fh, so add it.

This is a very basic conversion. I can't test this on real hardware,
so I didn't dare to also convert the driver to start using the
v4l2-mem2mem ioctl/fop helpers.
