Merge branch 'pci/msi' into next
* pci/msi:
PCI/MSI: Make pci_enable_msi/msix() 'nvec' argument type as int
PCI/MSI: Return -ENOSYS for unimplemented interfaces, not -1
PCI/MSI: Return msix_capability_init() failure if populate_msi_sysfs() fails
s390/PCI: Remove superfluous check of MSI type
s390/PCI: Fix single MSI only check
PCI/MSI: Export MSI mode using attributes, not kobjects
