    PCI: connect struct pci_dev to struct pci_slot · cef354db
    Alex Chiang authored
    The introduction of struct pci_slot (f46753c5)
    added a struct pci_slot pointer to struct pci_dev, but we forgot to
    associate the two.
    
    Connect the two structs together; the interesting portions of the object
    lifetimes are:
    
    	- when a new pci_slot is created, connect it to the appropriate
    	  pci_dev's. A single pci_slot may be associated with multiple
    	  pci_dev's, e.g. any multi-function PCI device.
    
    	- when a pci_slot is released, look for all the pci_dev's it was
    	  associated with, and set their pci_slot pointers to NULL
    
    	- when a pci_dev is created, look for slots to associate with.
    
    Note -- when a pci_dev is released, we don't need to do any bookkeeping,
    since pci_slot's do not have pointers to pci_dev's.
