I think it's most appropriate to keep tuner_ops.info.frequency_min|max , since it is the tuner that we're talking about. If the demodulator itself does not have such limitations, then we should not have such a field in the demod ops.info section.
I believe that this is leftover from before Andrew's original dvb tuner refactoring. Cheers, Mike _______________________________________________ linux-dvb mailing list [email protected] http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
