Hello,
You can try to fix it like that, but it is not proper way. It is kinda
of hack which can just work or not. Proper way is to fix that tuner
driver correctly and if it was used with zl10353 demoed fix that driver
too to support IIRC IF/RF agc settings.
regards
Antti

The patch fixes frequency selection for some UHF frequencies e.g.
channel 32 (562 MHz) on the qt1010 tuner. For those in the UK,
this now means they can tune to the BBC channels (tested on a Compro
Vista T750F).
One example of problem reports of the bug this fixes can be read at
