On some platforms such as that based on x86, ia64 etc, root bus is
created with parent node passed in as NULL to pci_create_root_bus().
On these platforms, the patch series "PCI: get DMA configuration from
parent device" when applied causes kernel crash. So add a check for this
in of_pci_dma_configure()
Wouldn't these arches have OF disabled and call an empty function?
Regardless, we still need this.

It might be an idea to read the subject line...
"fix BUG: unable to handle kernel"
Russell,
I will fix the subject as "fix BUG: unable to handle kernel NULL
pointer" and re-send.
Thanks
Murali
which is meaningless. It needs a much better subject line before it can
be committed.
