Subject: [PATCH v10 09/10] PCI: Assign unassigned bus resources in pci_scan_root_bus()
Date: Mon,  8 Sep 2014 14:54:31 +0100

In-Reply-To: <1410184472-17630-1-git-send-email-Liviu.Dudau@arm.com>

Sender: linux-arch-owner@vger.kernel.org
List-ID: <linux-pci.vger.kernel.org>

If the firmware has not assigned all the bus resources and
we are not just probing the PCIe busses, it makes sense to
assign the unassigned resources in pci_scan_root_bus().
