[patch 20/26] V4L: ivtv: fix udma yuv bug

[Greg KH <gregkh@suse.de>]

2.6.22-stable review patch.  If anyone has any objections, please let us
know.

------------------

From: Ian Armstrong <ian@iarmst.demon.co.uk>

Based on cb50f548c0ee9b2aac39743fc4021a7188825a98 in mainline

[PATCH] V4L: ivtv: fix udma yuv bug

Using udma yuv causes the driver to become locked into that mode. This
prevents use of the mpeg decoder & non-udma yuv output.

This patch clears the operating mode when the device is closed.
