Stephan Gerhold ed7ac37fde virtio_mmio: Add missing PM calls to freeze/restore ... Most virtio drivers provide freeze/restore callbacks to finish up device usage before suspend and to reinitialize the virtio device after resume. However, these callbacks are currently only called when using virtio_pci. virtio_mmio does not have any PM ops defined. This causes problems for example after suspend to disk (hibernation), since the virtio devices might lose their state after the VMM is restarted. Calling virtio_device_freeze()/restore() ensures that the virtio devices are re-initialized correctly. Fix this by implementing the dev_pm_ops for virtio_mmio, similar to virtio_pci_common.
