We explicitely made sure to not enable -Werror by default, because different versions of gcc will generate different set of warnings making it roughly impossible to use -Werror by default (say, newer versions of gcc with more clever warnings trying to compile old commits while bisecting) -- Damien

I'm not sure what's happened to the drm code in linux-next - it's exploding all over the place. Did someone turn on -Werror without doing anywhere near enough testing?
