I submitted a patch for this already:

http://patchwork.ozlabs.org/patch/373209/

Not sure how to deal with that, as Lucas indicated that it conflicts with
another patch of his. I guess I could just apply my patch as-is to fix the
current bug and let Linus deal with the merge conflict later.

Alternatively, we can turn this driver into builtin-only like some of
the other PCI host controllers. Not as nice, but gets rid of the bug
without introducing a conflict.

Jingoo, Mohit, Bjorn, any other opinions?
