Do not check whether the pointer passed to ACPI add callbacks is NULL as
it is earlier dereferenced anyway in the bus-level probe callback,
acpi_device_probe().
Do not check the value of acpi_disabled in fujitsu_init(), because it is
already done by acpi_bus_register_driver(), which is the first function
called by fujitsu_init().
