This part makes little sense to me for two reasons.

1) David Miller handles stable submission himself
 ( Documentation/networking/netdev-FAQ.txt )

2) We are not supposed to make sure old kernels will compile with
future compilers.

That would need a lot of work and potential new bugs, not worth the
time.

Otherwise your patch looks fine really ;)
