and that thread has a different target being some dvb tools which
access a device in /dev/dvb/*/* - it can be justified somehow to
mandate a protocol that all applications to open a ./frontend*
device (and to keep it open) when accessing a dvb/* device. However,
I am speaking of the usual v4l device where applications do not
expect to follow a certain protocol. That's subtly different, one
can not just say "fix your applications".

Theoretically, the v4l/ devices even allow to tune (_FLAG_TUNER),
exposing themselves as the frontend device to the videodev per se.
(well, _frequency is not all there is a dvb stream). Therefore, and
from the same theory, one might say that opening a v4l device
must be registered internally as a frontend counter increment.

Perhaps one could go the other way round: to disallow to open()
the videodev unless a frontend* is open (e.g. some szap panel),
so the user is not confused about the status. Naaaah, me not
like it. Anyone...
