Enable pci device as wakeup event source
int __pci_enable_wake(struct pci_dev * dev, pci_power_t state, bool runtime, bool enable);
dev
PCI device affected
state
PCI state from which device will issue wakeup events
runtime
True if the events are to be generated at run time
enable
True to enable event generation; false to disable
This enables the device as a wakeup event source, or disables it. When such events involves platform-specific hooks, those hooks are called automatically by this routine.
Devices with legacy power management (no standard PCI PM capabilities) always require such platform hooks.
0 is returned on success -EINVAL is returned if device is not supposed to wake up the system Error code depending on the platform is returned if both the platform and the native mechanism fail to enable the generation of wake-up events
