[PATCH v5 1/4] virtio: split device_register into device_initialize and device_add
In order to make caller do a simple cleanup, we split device_register into device_initialize and device_add. device_initialize always succeeds, so the caller can always use put_device when register_virtio_device faild.

[PATCH v5 4/4] virtio_remoteproc: correct put_device virtio_device.dev
rproc_virtio_dev_release will be called iff virtio_device.dev's reference count drops to 0. Here we just put vdev.dev, and then rproc->dev's cleanup will be done in rproc_virtio_dev_release.

[PATCH v3 0/5] proper cleanup if fail to register_virtio_device
Hi, Patch1 add a helper to get virtio_device's status which will be used later. Patch2~4: check virtio_device's status is RTIO_CONFIG_S_ACKNOWLEDGE or not, if so use put_device otherwise use kfree. Patch5: add comments for virtio_register_device help caller do a proper cleanup if got failure. weiping zhang (5): virtio: add helper virtio_get_status virtio_pci: don't kfree device
