Don't bother. IIRC, the function is not working correctly for the MT2060. The
self-calibration does not work. The IF-offset must be set per-device during
production and usually is programmed into an eeprom on the cards. Simply apply
it to the mt2060_attach-function (see mt2060.h).

Use a callback in the config struct of either the demod or the tuner driver. It
is not always the right solution to put specific functionality for one or two
devices into a generic interface or in the dvb_tuner_ops case into the abstract
