This is likely needed for DVB-T2 and DVB-S2 too.

Just coding style:
		} else if (!dvb_new_freq_is_needed(dvb_file->first_entry, entry,
  					    freq, pol, shift))

We use the same coding style here as the one defined at the Kernel.

Shouldn't it be: !strcasecmp(entry->lnb, parms->lnb->alias)? Or maybe just
remove this test.
