It moved the code from pci_msi_init_pci_dev() to a new function named pci_msi_setup_pci_dev(), called by pci_setup_device(). The pseries PCI probing code does not call pci_setup_device(), so since the aforementioned commit the function pci_msi_setup_pci_dev() is not called and MSI/MSI-X interrupts are left enabled. Additionally because dev->msi_cap/msix_cap are not initialised no driver can ever enable MSI/MSI-X. To fix this, the pseries PCI probe should manually call pci_msi_setup_pci_dev(), so this patch makes it non-static.
