For a pci bridge device, if we don't override the name with custom code, the bus will be addressed as <id>.0, where id is the id specified by the user. Since PCI Bridge devices have a single bus each, we don't need the index: address the bus using the parent device name. This is better since this way users don't care about our internal bus/device distinctions. As far as I could see, we only have built-in bridges at this point which always override the name. So this change will only affect ioh3420.c. Comments? Signed-off-by: Michael S. Tsirkin <mst@redhat.com> --- hw/pci_bridge.c | 10 ++++++++++ 1 files changed, 10 insertions(+), 0 deletions(-)
