[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.
