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 drivers/misc/mic/vop/vop_main.c | 20 +++++++++++++------- drivers/remoteproc/remoteproc_virtio.c | 13 +++++++++++-- drivers/virtio/virtio.c | 18 +++++++++++++++--- drivers/virtio/virtio_pci_common.c | 8 ++++++-- 4 files changed, 45 insertions(+), 14 deletions(-) -- 2.9.4 _______________________________________________ Virtualization mailing list Virtualization@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/virtualization
