From 9785d646c10b0707412516ffe56b71b9eb18861f Mon Sep 17 00:00:00 2001 From: Grant Grundler Date: Wed, 28 Jan 2009 22:30:55 -0700 Subject: parisc: fix wrong assumption about bus->self Kenji Kaneshige posted a patch series to linux-pci to fix a wrong assumption about pci_bus->self==NULL for all PCI host bus controllers. While PARISC platforms to not behave this way, I prefer to have the code consistent across architectures. The following patch replaces pci_bus->self with pci_bus->parent when used as a test to check for "root bus controller".
