During EEH PCI hotplug activity kernel unloads and loads the driver, causing character device to be unregistered(aac_remove_one).When the driver is loaded back using aac_probe_one the character device needs to be registered again for the AIF management tools to work. Fixed by adding code to register character device in aac_probe_one if it is unregistered in aac_remove_one.
