Ok, applied this series to my linux-next branch, it looks pretty
reasonable to me.

For future patches, please cc me, and include the subsystem in the
subject, along with a specific description of the patch, e.g. "PCI: add
PCIe fundamental reset interface", "PCI: document PCIe fundamental
reset", or for arch specific patches, "PCI/powerpc: implement support
for PCIe fundamental reset".
