Well, if we reuse Michael's statistics:
- 58 drivers call pci_enable_msix() - 24 try a single allocation and then fallback to MSI/LSI - 19 use the loop style allocation - 14 try an allocation, and if it fails retry once
...then I expect most of 19/58 (loop style) could be converted to pcim_enable_msix() and pcim_enable_msix_range() and all of 14/58 (single fallback) should be converted to pcim_enable_msix() users.
