[linux-dvb] Patch for broken radio in XC2k and XC3k tuners

Hi, I am very supprised that no one complains about broken radio support 
on devices with XC2k and XC3k tuner, it is broken since commit:

V4L/DVB: tuner-xc2028: fix tuning logic to solve a regression in Australia

from date 19.3.2010

BUG is present in current kernel stable version 2.6.38 and also olders 
like 2.6.37, fix is very trivial.

I tested this fix with Leadtek DTV1800H radio and it works great, before 
this fix I can listen so much of noise on tuned frequency (so something 
wrong with tuning).

Feel free to modify this patch :)
