Namely, the device's state should not be too high power for given system sleep state and, if the device is supposed to be able to wake up the system, its state should not be too low power for the wake up to be possible). For this purpose, the ACPI core needs to implement the set_target() method in 'struct pm_ops' and store the target system sleep state passed by the PM core in a variable. Signed-off-by: Rafael J.
