From f92d4e29d785f1d4217dee7f1ae6ff7140547ed5 Mon Sep 17 00:00:00 2001 From: Kenji Kaneshige Date: Tue, 17 Feb 2009 14:15:16 +0900 Subject: [PATCH] PCI: fix wrong assumption in pci_read_bridge_bases Current pci_read_bridge_bases() has an assumption that pci_bus->self is NULL on the pci root bus (It checks pci_bus->self to see if the pci bus is root bus). But is might not true on some platforms. We must check pci_bus->parent instead.
