Use pci_enable_msix_{exact,range} for now, as I told you before.
That still results in twice as many MSI-X being provisioned than are needed.
How so? Except for the return value, a pci_enable_msix_exact call with the
same arguments as your previous pci_enable_msix will work exactly the
same.
Sorry, I think it was my misunderstanding. I didn't realize that we
had essentially renamed the function, but left the functionality
mostly unchanged.
Does this mean you're OK with this patch?
Yes. I have re-written my GPIO driver to use the newer functions, so I
withdraw my objections to the patch.
Thanks,

I know it may require some
work on out-of-tree drivers and so on, but if that work is possible
and you don't actually lose functionality, I'm OK with this patch.
