I'd rather not touch that code. How about adding a comment about
the fact that it should use dma_mmap_coherent()?

Maybe the real question is if there is anyone that actually cares
for this driver, or if we are better off just removing it?

Same is true for various other virt_to_bus using drivers, e.g. the
grotty atm drivers.

I would appreciate if somebody would removes the driver from the linux kernel. I suggested that some years ago 2014-06-23 (just scroll down):
https://sourceforge.net/p/mjpeg/mailman/mjpeg-users/?viewmonth=201406

You should also find that thread in the kernel-janitors@xxxxxxxxxxxxxxx and linux-media@xxxxxxxxxxxxxxx Mailinglist archive.

I know of one person that is still using this old type of card's but he uses a 2.6.x Kernel on a old machine, using old software releases.
https://sourceforge.net/p/mjpeg/mailman/mjpeg-users/?viewmonth=201709

That type of card were introduced about ~20 years ago. I think it is a good moment to say goodbye to that type of cards.
