The fix:

commit 3be434f0244ee059432f92de7e891ee514f41738
Author: Jesse Barnes <jbarnes@virtuousgeek.org>
Date:   Fri Jun 11 13:08:37 2010 -0700

    Revert "PCI: create function symlinks in /sys/bus/pci/slots/N/"
    
    This reverts commit 75568f8094eb0333e9c2109b23cbc8b82d318a3c.
    
    Since they're just a convenience anyway, remove these symlinks since
    they're causing duplicate filename errors in the wild.
