This code is wrong as I should have coded it as SYS_DVBC, instead of SYS_DVBS & friends. Anyway, this check has other problems 1) it does some "magic" by assuming that all QAM modulations are below QAM_AUTO; 2) it checks modulation parameters only for one delivery system. Or the core should check invalid parameters for all delivery systems, or it should let the frontend drivers do it; 3) frontend drivers should already be checking for invalid parameters (most of them do it, anyway); 4) not all modulations are mapped at fe->ops.info.caps, so it is not even possible to check for the valid modulations inside the core for some delivery systems; 5) The core check is incomplete anyway: it only checks for a few parameters. If moved into the core other parameters like bandwidth and fec should also be checked; 6) 2nd gen DVB-C uses OFDM. So, that test would fail for it.
