Wysocki Use the observation that the initial status check for ACPI_BUS_TYPE_PROCESSOR objects can be carried out in the same way as for ACPI_BUS_TYPE_DEVICE objects and it is not necessary to fail acpi_add_single_object() if acpi_bus_get_status_handle() returns an error for a processor (its status can be set to 0 instead) to simplify acpi_add_single_object(). Accordingly, drop the "sta" argument from acpi_init_device_object() as it can always set the initial status to ACPI_STA_DEFAULT and let its caller correct that later on. Signed-off-by: Rafael J.
