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

[weiping zhang <zwp10758@gmail.com>]

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 device's status then determine use
   put_device or kfree.

v1->v2:
 * virtio_pci: add comments in commit message for why using put_device
 * virtio_vop: also use put_device int _vop_remove_device
weiping zhang (4):
  virtio: split device_register into device_initialize and device_add
  virtio_pci: don't kfree device on register failure
  virtio_vop: don't kfree device on register failure
  virtio_remoteproc: don't kfree device on register failure
