Why not add a minimum number to pci_enable_msix(), i.e.: pci_enable_msix(pdev, msix_entries, nvec, minvec) ... which means "nvec" is the number of interrupts *requested*, and "minvec" is the minimum acceptable number (otherwise fail).
Which is exactly what Ben (the other Ben :-) suggested and that I supports... Cheers, Ben.
