As pci_find_device is going away need to replace it. This file did not use the dev returned
from pci_find_device so is replaceable by pci_dev_present. I was not able to test it
as I do not have the hardware.

I think this check should just go away completely.  

We don't have such silly warnings in any other driver.

Good point.  Especially as pci_module_init() can never return -ENODEV
anymore :)

Why the extra brackets?  I see their use for

	return (a == b);

but

	return pci_module_init(&bttv_pci_driver);

isn't at all ambiguous.

Kraxel introduced this  check because of the confusion  with the "old"
and "new" WinTV cards. The older one had a bt848 chip, the newer one a
connexant 878, and only the older one was supported by Linux.

Now that we support both, this printk is rather counterproductive.

Yep, that was the reason.  It's pretty much obsolete these days through
as we have a working (well, sort of, depending on the tv norm sound may
be a problem ...) driver for these cards in mainline.  Just dropping
that now is perfectly fine.
