From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
None of the existing users of struct acpi_dock_ops actually needs the
first argument of its member functions, so redefine those functions
to take only two arguments, the event type and data pointer, and
update the users of struct acpi_dock_ops accordingly.
