this *should* work. The Bay driver registers with the dock driver to get
dock events:
/* if we are on a dock station, we should register for dock
* notifications.
*/
if (bay_is_dock_device(handle)) {
bay_dprintk(handle, "Is dependent on dock\n");
register_hotplug_dock_device(handle, bay_notify, new_bay);
}
then, on undock the dock driver calls the bay_notify function and passes
it the EJECT request event. This causes the bay driver to emit an event to
userspace.
case ACPI_NOTIFY_EJECT_REQUEST:
kobject_uevent(&dev->kobj, KOBJ_CHANGE);
break;
default:
an event to userspace.
