The problem with USERPTR is that it's completely unknown what the requirements
for the memory are. Is it enough to be some memory? Does it need to be
physically contiguous? Does it need to be something else?

This information can't be retrieved via V4L2 and is completely dependant on the
hardware and driver AFAIK. Due to this I don't think it makes sense to
generically implement USERPTR support as it will never work reliably in all
situations.
