From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bjorn Helgaas Subject: [PATCH v3 18/34] mn10300/PCI: convert to pci_scan_root_bus() for correct root bus resources Date: Fri, 28 Oct 2011 16:27:02 -0600 Message-ID: <20111028222702.30729.65118.stgit@bhelgaas.mtv.corp.google.com> References: <20111028222432.30729.8431.stgit@bhelgaas.mtv.corp.google.com> Mime-Version: 1.0 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: 7bit Return-path: Received: from smtp-out.google.com ([216.239.44.51]:35745 "EHLO smtp-out.google.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S932828Ab1J1W1G (ORCPT ); Fri, 28 Oct 2011 18:27:06 -0400 In-Reply-To: <20111028222432.30729.8431.stgit@bhelgaas.mtv.corp.google.com> Sender: linux-arch-owner@vger.kernel.org List-ID: To: linux-pci@vger.kernel.org Cc: linux-arch@vger.kernel.org, David Howells Convert from pci_scan_bus() to pci_scan_root_bus() and remove root bus resource fixups. This fixes the problem of "early" and "header" quirks seeing incorrect root bus resources.
