    Applying a patch like s/virt_to_bus/virt_to_phys/ makes it more
    difficult to find the right spots to change later.

    Patience :) We will fix i810_audio and the other notables. As I noted
    in the other message just now, i810_audio and bttv fixes are already
    floating around, and hopefully should appear on lkml or in a Linus
    pre-patch soon...

    I can tell you it is -not- a waste of time. It's not a waste of time
    when a vendor appears out of nowhere, having copied a driver of yours.
    Since you did it right(tm), the vendor driver is portable, even though
    its original source was for x86-only hardware. It's not a waste of time
    when people copy your code or learn from your code. It's not a waste of
    time when spiffy new x86 hardware appears that has useful IOMMU stuff,
    making a driver's use of the PCI DMA API automatically useful for that
    new hardware.

    I agree with Linus that there is little motivation for someone to
    continue patching a driver, after they have fixed the problem they set
    out to fix. But that is not the same as saying driver portability is
    worthless... far from it.
