SRU Justification
[Impact]
When I hot-add a NIC to a Ubuntu 20.04 VM (“5.13.0-1023-azure
#27~20.04.1-Ubuntu”), I get the the below call-trace.
Please include the March-2022 fix: “Drivers: hv: vmbus: Fix initialization of
device object in vmbus_device_register()”
(https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3a5469582c241abca22500f36a9cb8e9331969cf)
BTW, this call-trace should be harmless to a non-CVM VM.
