Hi Greg,

I saw you backported my fix for this is to stable/linux-4.9.y, but I
don't see it
in 4.4.y. Can you add it here as well, or do you want help resolving a conflict?

The upstream commit is  b4391db42308 ("netlink: fix
nla_put_{u8,u16,u32} for KASAN")

This is then the only remaining warning in 4.4. We've discussed it a few times
before but not concluded on how to best fix it. The warning exists only in
the android trees, mainline and stable don't have it.
