Comment 25 for bug 459523

I tried this patch, on 2.6.24-23-rt and 2.6.31-14-generic
.
On the first, it appears to work fine. Thanks again Rob!

On the second, while the kernel seems happy I am unable to get any
applications to tune the card, when I use the latest v4l tree + Rob's
patch (40705fec2fb2 tip).

 * dvbscan fails with 'unable to query frontend status'

 * vlc is unable to tune as well
[0x9c2cf50] dvb access error: DVB-T: setting frontend failed (-1):
Invalid argument
[0x9c2cf50] dvb access error: DVB-T: tuning failed
[0xb7400c18] main input error: open of `dvb://frequency=177500' failed: (null)

 * w_scan fails a bit more informatively

Presumably this is all understood and expected i.e. application
authors are updating their code. Or do I have to go file wishlist bugs?
I see w_scan have updated to 5.1 as of late September.
