NAME
       __pci_enable_wake - enable PCI device as wakeup event source

SYNOPSIS
       int __pci_enable_wake(struct pci_dev * dev, pci_power_t state, bool runtime, bool enable);

ARGUMENTS
       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

DESCRIPTION
       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.

       RETURN VALUE: 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
