Sure. I'll wait for Stakanov to test, in order to add his tested-by.

For now, I'm enclosing the patch with the current tags added to it.

[PATCH] media: dvb-pll: fix tuner frequency ranges

Tuners should report frequencies in Hz. That works fine on most
drivers, but, in the case of dvb-pll, some settings are for
satellite tuners, while others are for terrestrial/cable ones.

The code was trying to solve it at probing time, but that doesn't
work, as, when _attach is called, the delivery system may be wrong.

Fix it by ensuring that all frequencies are in Hz at the per-tuner
max/min values.

While here, add a debug message, as this would help to debug any
issues there.

It fixes the following bug:
