"ret" is unused in that function, causing a warning which breaks the
build since we have -Werror. I'm fixing that locally but be more careful
next time please.

Ben.

Sorry about that warning, I clearly missed that. I guess you
do a custom build with -Werror flag enabled, unlike what the normal
Makefile does?

Thanks,
