Yeah, we call pci_create_sysfs_dev_files() from pci_sysfs_init() and from pci_bus_add_device(). I haven't figured out why it is that creating other sysfs files, e.g. rom files, capabilities, etc. don't also result in duplicate entries while the slots do. Clearly my expectation was incorrect for the cases when pci_create_sysfs_dev_files() gets called on the different architectures. Anyhow, thanks for the revert Jesse. I wish I had more time/energy to dig into this right now, but I really don't.
