Subject: [PATCH v2 1/3] base: mark 'no_warn' as unused

Fix the following build warning:

  drivers/base/module.c:36:6: error: variable 'no_warn' set but not used [-Werror,-Wunused-but-set-variable]
        int no_warn;

This variable is used to remove another warning, but causes a warning
itself. Mark it as 'unused' to avoid that.
