Well, this is the thing: W=1 might make sense *sometimes* because it
enables a couple of warnings. One of them is -Wmissing-prototypes which
doesn't make sense for stable, as explained earlier.

So you need to either

* disable -Wmissing-prototypes only which means stable-specific patch
and stable folks don't like that.

or

* analyze the reports *before* sending them out. You could simply not
send reports which come solely from -Wmissing-prototypes warnings.

or

* patch the stable tree locally with your own patch

or

* ...

It all depends on what is done easier in your infra.

HTH.
