Remove a pci device and any children
void pci_stop_and_remove_bus_device(struct pci_dev * dev);
dev
the device to remove
Remove a PCI device from the device lists, informing the drivers that the device has been removed. We also remove any subordinate buses and children in a depth-first manner.
For each device we remove, delete the device structure from the device lists, remove the /proc entry, and notify userspace (/sbin/hotplug).
