Seems to be missing an "iwlwifi:" or so prefix, but I guess we can add
it when we take the patch ...

Sorry.  Not sure why that happened.  I'll look into it.

Is there any way we could catch (sparse, or some other script?) that
struct reorganising won't break the condition needed ("within a
structure that contains at least two more bytes")?

What kind of reorganizing could happen?  Do you mean that the programmer 
might do at some time in the future, or something the compiler might do?
