There is also the cover-letter (does anyone in the community ever read those?) which explicitly states: "Patch "Remove devres from pci_intx()" obviously reverts the previous patches that made drivers use pci_intx_unmanaged(). But this way it's easier to review and approve. It also makes sure that each checked out commit should provide correct behavior, not just the entire series as a whole."
