If acpi_install_notify_handler() for a bay device fails, the bay driver is
superfluous. Most likely, another driver (like libata) is already caring
about this device anyway. Furthermore,
register_hotplug_dock_device(acpi_handle) from the dock driver must not be
called twice with the same handler. So clean up and exit.
