powerpc/PCI: Disable MSI/MSI-X interrupts at PCI probe time in OF case
Since commit 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI"), the setup of dev->msi_cap/msix_cap and the disable of MSI/MSI-X interrupts isn't being done 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 exhibits as drivers not being able to enable MSI, eg: bnx2x 0000:01:00.0: no msix capability found This patch calls pci_msi_setup_pci_dev() explicitly to disable MSI/MSI-X during PCI probe time on pSeries platform. Fixes: 1851617cd2da ("PCI/MSI: Disable MSI at enumeration even if kernel doesn't support MSI") [mpe: Flesh out change log and clarify comment] Signed-off-by: Guilherme G.
