Hi all, In the PCI config access path, the *_pcie_valid_device() functions in the dwc, altera, rockchip, and xilinx drivers all check whether the link is up. I think this is racy because the link may go down after we check but before we perform the config access. What would blow up if we removed the *_pcie_link_up() checks? I'd like to either remove the checks or add comments about why the race is acceptable. If we've covered this before, I apologize. Adding a comment will keep me from pestering you about this again in the future. Bjorn
