For me, based on Linus's master, this applies with the previous series.

It seems to me that this issue only exists on linux-next, the reason
being that git searches for struct pci_devres in line 811, but on
linux-next, because of previous additions, the struct moved to line
827, and poor git can't find it anymore.

I could fix that and provide a v4.
