Re: [PATCH] Fix to qt1010 tuner frequency selection (media/dvb)
I think my problem frequency has also been at the later spot. It is possible there is something more complicated going on at 474 MHz - so based on your testing, it's best to apply just the latter change, at least for now.

Re: [PATCH] Fix to qt1010 tuner frequency selection (media/dvb)
I haven't gotten any feedback, and didn't see any comments on the lists
(though I've checked them only occasionally), so I think you're probably
right it fell between the cracks.

This patch means I can now finally tune to all the BBC channels (which are on
channel 31 (554 MHz) in my area). This should definitely go to stable, as I've
also seen other similar reports for users who can't tune to various channels
in the affected ranges here using qt1010.
