From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
In order for the ACPI dock station code to be able to use the callbacks pointed to by the ACPI device objects' hotplug contexts add a .fixup() callback pointer to struct acpi_hotplug_context. That callback will be useful to handle PCI devices located in dock stations.
