Subject: x86/PCI: make pci=lastbus=255 work when acpi is on
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e42d1fe804408c57506a5326252b4db29958a7fb;p=linux-beck.git

x86/PCI: make pci=lastbus=255 work when acpi is on

Impact: scan more peer root buses even acpi is used

Move pci_bios_fixup_peer_bridges out of pci_legacy_init and into
pci_subsys_init.  This allows pci_bios_fixup_peer_bridges to be called
even pci_apci_init is driving PCI initialization.
