ACPI / PM: Do not apply ACPI_SUCCESS() to acpi_bus_get_device() result
Since the return value of acpi_bus_get_device() is not of type acpi_status, ACPI_SUCCESS() should not be used for checking its return value. Fix that. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Reviewed-by: Mika Westerberg <mika.westerberg@linux.intel.com>
