Minor change in behaviour would perhaps be worth acknowledging in the
commit message (since you check ndev for NULL later now), and a Fixes
tag would be good.

But the looks pretty straightforward and correct!

Hi,
Yeah, it looks the minor behavior change doesn't matter, because IMO the 
'nvdev' can only be NULL when the NIC is being removed, or the MTU is
being changed, etc.

The Fixes tag is:
Fixes: 776e726bfb34 ("netvsc: fix RCU warning in get_stats")

If I should send a v2, please let me know.

Thanks,
