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

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
