[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 v4 0/4] use put_device to cleanup resource
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.

[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.

Maybe add the same description as in your virtio_mmio patch so that it
is clear why the kfree() is not ok?
