Your interface for this is really horrible ;-)


+	int bars = pci_select_bars(pdev, IORESOURCE_MEM);

-	if (pci_enable_device(pdev))
+	if (pci_enable_device_bars(pdev, bars))
		goto out;
-	if (pci_request_regions(pdev, LPFC_DRIVER_NAME))
+	if (pci_request_selected_regions(pdev, bars, LPFC_DRIVER_NAME))
		goto out_disable_device;


Please make this something like:

	if (pci_enable_device_noioport(pdev))
		goto out;
	if (pci_request_regions(pdev, LPFC_DRIVER_NAME))
		goto out_disable_device;

as in:

 - get rid of this awkward pci_select_bars function, the pci_enable* function
   should do all the work and add a flag to struct pci_dev so that all other
   functions do the right thing.



No. Your idea is very similar to the idea of previous version of my patche
which had a bug. The problem is that it doesn't work if pci_request_regions()
is called before pci_enable_device*() (This is the correct order, though so
many drivers breaks this rule).

Thanks,
