dvb_new_freq_is_needed() was integrated to dvb_new_entry_is_needed(),
and dvb_scan_add_entry() was added a new parameter.
As those changes broke API/ABI compatibility,
restore the original functions.

I suppose you introduced the new functions to generalize the API.
Can't you keep the new functions and make dvb_new_freq_is_needed a thin
wrapper around them?

Thanks,
Gregor

Hi,

the patch is aimed to do just as you wrote,
i.e. add wrapper funcs with the original names.
sorry for my bad english.
