Bluetooth: Add hook for driver to prevent wake from suspend
Let drivers have a hook to disable configuring scanning during suspend.
Drivers should use the device_may_wakeup function call to determine
whether hci should be configured for wakeup.
For example, an implementation for btusb may look like the following:
bool btusb_prevent_wake(struct hci_dev *hdev)
{
struct btusb_data *data = hci_get_drvdata(hdev);
return !device_may_wakeup(&data->udev->dev);
}
