Yes, I saw this build failure in the linux-next logs, but I'm not sure what
to do about it. I can't adopt Yinghai's solution in my tree since my tree
is based off of Linus's tree which doesn't have "bus->busn". I suppose I
could publish two trees to linux-next, one based off of Bjorn's "pci" tree
(I assume) and one with all the non-PCI arch/tile stuff (my current
linux-next tree).
I admit I was lazily assuming I would just fix this once the trees collided
during the 3.6 merge window :-)
