When make with EXTRA_CFLAGS=-W, it will report error.
so give a check in Makefile.

Perhaps, it would be good idea to fight the original problem.
I mean, fix warnings where possible. Example: there are lots of
"unused parameter" ones. Where it is false warning, add __maybe_unused
attribute. Like this:

thank you for your suggestion.
after this patch applied, I will do for others (let you as signed-of-by, too).

Well, agree; -W triggers lots of warnings, I suspect all other places that use
-Werror should be problematic. Worth fixing all others? Quick look for v3.8 raises:

if my another 'beautify code' patches are applied into next-* tree.
(that means most of members think it is a good idea).
I will process the original problems (when processing, also cc to you).
