Since the commit 1851617cd2 ("PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI"), MSI/MSI-X interrupts aren't being disabled at PCI probe time, as the logic responsible for this was moved in the aforementioned commit from pci_device_add() to pci_setup_device(). The latter function is not reachable on PowerPC pSeries platform during Open Firmware PCI probing time. This patch calls pci_msi_setup_pci_dev() explicitly to disable MSI/MSI-X during PCI probe time on pSeries platform. Signed-off-by: Guilherme G.
