Fix header file warnings when CONFIG_ACPI is not enabled:

include/acpi/acpi_bus.h:443:42: warning: 'struct acpi_bus_type' declared inside parameter list
include/acpi/acpi_bus.h:443:42: warning: its scope is only this definition or declaration, which is probably not what you want

Hi Randy,
with your patch applied and CONFIG_ACPI=n, I still get:

include/acpi/acpi_bus.h:445:12: warning: ‘register_acpi_bus_type’ defined but not used [-Wunused-function]
include/acpi/acpi_bus.h:446:12: warning: ‘unregister_acpi_bus_type’ defined but not used [-Wunused-function]

so I think I prefer the patch below.

thanks,

Hi Len,

I'd love to see your failing .config file if you have it or can
reproduce it.  My patch still works for me.
