You are passing the wrong things around :) A struct pci_bus is a struct class_device, not a struct device. I think you need to rethink your goal of putting the files into the pci device directory, or just put the files into the proper /sys/class/pci_bus/* directory as your code assumes is happening. thanks, greg k-h
