 {
-	struct acpi_device *device = NULL;
-	struct acpi_driver *driver;

 	ACPI_DEBUG_PRINT((ACPI_DB_INFO, "Notification %#02x to handle %p\n",
 			  type, handle));
 
-	blocking_notifier_call_chain(&acpi_bus_notify_list,
-		type, (void *)handle);

By the way, there is exacly one user of this chain, which is dock.c.

What about convering that to something different and dropping the chain to
start with?

I agree.  I will look further to see what interface we can use to
replace it.
