They do not apply cleanly on top of the remoteproc virtio config patches from Sjur, but it merges fine. CAIF will use this new host virtio ring implementation. Ido,

Hi, The main change is split device_register into 2 sperate calls: device_initalize() and device_add, and then the caller can use put_device safety when fail to register_virtio_device. v3->v4: * split device_register into device_initialize and devicea_add that the caller can always use put_device when fail to register virtio device. v2->v3: * virtio: add new helper do get
