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

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:

linux$ find . -name Makefile | xargs grep -e -Werror

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

  :-)
