IMO, the better would be not to initialize frequency ranges at the
demods (since this is tuner stuff).
If you are afraid of having a tuner driver with improper values, add a
check can be added, at dvb frontend core, to use the maximum allowed
frequency range, if frequency_max is not defined. The better, however,
is to fix the tuner drivers without frequency limits.
Removing the frequency ranges from demods have two advantages:
1) Avoid bogus values at demods;
2) It helps to decrease the BSS size of the module, used initialize
those two variables that are useless at demod context.
