Ok, I let Or handle that. Maybe he wants to add a user of it, instead.

I also noticed that coverty scanner found a couple of other issues,
e.g. outlen_write() in mlx5/core/cmd.c does a kzalloc() without
doing sanity checks on the user-passed allocation size, e.g. it
could even be a negative value passed to it.
