[linux-dvb] Airstar-HD5000-PCI LGDT220X frontend

[Taylor Jacob]

Get my patch from

http://www.digitalregime.com/patches/hd5000.patch

The b2c2 driver in 2.6.13 AND dvb-kernel does NOT attempt to attach the lgdt3303
frontend.. This patch above DOES..

The patch above is against dvb-kernel, but may also apply decently against
linux-2.6.13..

I want to clean this patch up just a tad before submiting it officially for
inclusion in dvb-kernel, but functionally that cleaned up patch will be the
same as what you see above..

If you have further questions please let me know..
