From 57283776b2b821ba4d592f61cad04d0293412740 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Thu, 11 Mar 2010 12:20:11 -0700 Subject: ACPI: pci_root: pass acpi_pci_root to arch-specific scan The acpi_pci_root structure contains all the individual items (acpi_device, domain, bus number) we pass to pci_acpi_scan_root(), so just pass the single acpi_pci_root pointer directly. This will make it easier to add _CBA support later. For _CBA, we need the entire downstream bus range, not just the base bus number. We have that in the acpi_pci_root structure, so passing the pointer makes it available to the arch-specific code.
