Called from just one place, so that should be ok.

Ok, I just killed it.

Actually, it is the other way around. BT_DBG adds the newline. I'll
remove it from the rest.

Probably not, removed.

Why not.

I am not sure bluetooth rules are same as ethernet. And notice that it
only errors out on 00:00:00:00:00:00 which seems like invalid address
to me.

I fixed the other ones.

Thanks,
