From 9e266ece2178784a1027e04a56c8547dc51b15ce Mon Sep 17 00:00:00 2001 From: Aaron Lu Date: Mon, 9 Sep 2013 09:57:12 +0930 Subject: [PATCH] virtio_pci: pm: Use CONFIG_PM_SLEEP instead of CONFIG_PM MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit 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.
