    virtio_pci: pm: Use CONFIG_PM_SLEEP instead of CONFIG_PM · 9e266ece
    Aaron Lu authored
    The virtio_pci_freeze/restore are defined under CONFIG_PM but is used
    by SET_SYSTEM_SLEEP_PM_OPS macro, which is defined under
    CONFIG_PM_SLEEP. So if CONFIG_PM_SLEEP is not cofigured but
    CONFIG_PM_RUNTIME is, the following warning message appeared:
    
    drivers/virtio/virtio_pci.c:770:12: warning: ‘virtio_pci_freeze’ defined but not used [-Wunused-function]
     static int virtio_pci_freeze(struct device *dev)
                ^
    drivers/virtio/virtio_pci.c:790:12: warning: ‘virtio_pci_restore’ defined but not used [-Wunused-function]
     static int virtio_pci_restore(struct device *dev)
                ^
    Fix it by changing CONFIG_PM to CONFIG_PM_SLEEP.
