PCI: Assign resources for hot-added host bridge more aggressively
When hot-adding an ACPI host bridge, use
pci_assign_unassigned_root_bus_resources() instead of
pci_assign_unassigned_bus_resources().
The former is more aggressive and will release and reassign existing
resources if necessary. This is safe at hot-add time because no drivers
are bound to devices below the new host bridge yet.
