Function Documentation

int acpi_device_sleep_wake	(	struct acpi_device *	dev,
		int	enable,
		int	sleep_state,
		int	dev_state
	)

acpi_device_sleep_wake - execute _DSW (Device Sleep Wake) or (deprecated in ACPI 3.0) _PSW (Power State Wake) : Device to handle. : 0 - disable, 1 - enable the wake capabilities of the device. : Target sleep state of the system. : Target power state of the device.

Execute _DSW (Device Sleep Wake) or (deprecated in ACPI 3.0) _PSW (Power State Wake) for the device, if present. On failure reset the device's wakeup.flags.valid flag.

RETURN VALUE: 0 if either _DSW or _PSW has been successfully executed 0 if neither _DSW nor _PSW has been found -ENODEV if the execution of either _DSW or _PSW has failed
