From 6a49d8120021897e139641062236215aac5d220e Mon Sep 17 00:00:00 2001 From: Yu Zhao Date: Sat, 22 Nov 2008 02:38:21 +0800 Subject: PCI: enhance pci_ari_enabled() Change parameter of pci_ari_enabled() from 'pci_dev' to 'pci_bus'. ARI forwarding on the bridge mostly concerns the subordinate devices rather than the bridge itself. So this change will make the function easier to use.
