[PATCH] PCI: make MSI quirk inheritable from the pci bus
It turns out AMD 8131 quirk only affects MSI for devices behind the 8131 bridge. Handle this by adding a flags field in pci_bus, inherited from parent to child. Signed-off-by: Michael S. Tsirkin <mst@mellanox.co.il> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
