Zoran is a driver for old hardware. I don't doubt that are people
out there still using it, but who knows?

I have a few those boards packed somewhere. I haven't work with PCI
hardware for a while. If needed, I can try to seek for them and
do some tests. I need first to unpack a machine with PCI slots...
the NUCs I generally use for development don't have any :-)

Anyway, except for virt_to_bus() and related stuff, I think that this
driver is in good shape, as Hans did a lot of work in the past to
make it to use the current media framework.
