[PATCH 0/5] virtio: S3 support, use PM API macro for init
Hello, Turns out S3 is not different from S4 for virtio devices: the device is assumed to be reset, so the host and guest state are to be assumed to be out of sync upon resume. We handle the S4 case with exactly the same scenario, so just point the suspend/resume routines to the freeze/restore ones. Once that is done, we also use the PM API's macro to initialise the sleep functions. A
