It is totally simple: without -Werror, you can build a kernel.  With it,
you cannot.

The ***warning*** is correct, there is something in the code that can be
improved.  That is why such things are warnings: the compiler can
produce useful output, there is no reason to scream bloody murder.

The main reason some people like -Werror is because they are too lazy to
look at the warning messages they get from normal builds.  Such
developers need potty training, this is not a reason to punish all more
reasonable people!
