Revision 0bd252de78d406485c896508c13a8f7a78ee8353 authored by Alex Williamson on 27 August 2014, 19:01:35 UTC, committed by Alex Deucher on 27 August 2014, 21:54:50 UTC
If we assign a Radeon device to a virtual machine, we can no longer assume a fixed hardware topology, like the GPU having a parent device. This patch simply adds a few pci_is_root_bus() tests to avoid passing a NULL pointer to PCI access functions, allowing the radeon driver to work in a QEMU 440FX machine with an assigned HD8570 on the emulated PCI root bus.
