Acked-by: Bjorn Helgaas <bhelgaas@google.com> If you update this patch for any reason, please update the subject like this: -PCI: quirk fixup for cavium invalid sriov link value. +PCI: Fix incorrect Cavium cn8xx SR-IOV Function Dependency Link This will make "git log --oneline drivers/pci/quirks.c" show more useful information and look more consistent. I assume somebody else will merge this patch along with your HWRNG driver.
