changeset 6bbf7a855d ("media: dvbdev: convert DVB device types into an enum")
added a new warning on gcc 6:
>> drivers/media/dvb-core/dvbdev.c:86:1: warning: control reaches end of non-void function [-Wreturn-type]
That's because gcc is not smart enough to see that all types are
present at the switch. Also, the current code is not too optimized.
So, replace it to a more optimized one, based on a static table.
