linux n内核驱动编译出错

我正在进行wifi驱动的移植，android SDK的版本是4.2.2 内核是3.2.0的，但是当我将驱动代码
加入到kernel里后，编译module时出现了如下错误：
CC [M] drivers/net/wireless/bcmdhd/wl_cfg80211.o

make[4]: *** [drivers/net/wireless/bcmdhd/wl_iw.o] 错误 1

make[3]: *** [drivers/net/wireless/bcmdhd] 错误 2
make[2]: *** [drivers/net/wireless] 错误 2
make[1]: *** [drivers/net] 错误 2
make: *** [drivers] 错误 2

我找到了上面说的结构体如下：
struct iw_handler_def {
const iw_handler *standard;
__u16 num_standard;

#ifdef CONFIG_WEXT_PRIV
__u16 num_private;
__u16 num_private_args;
const iw_handler *private;
#endif

};

是不是因为kernel里面CONFIG_WEXT_PRIV没配置上啊，如果是的话要怎么配置啊，为什么我在内核里没找到这个选项啊， 而且我在.config文件中增加了CONFIG_WEXT_PRIV=y 再编译也还是出错，为什么啊？

哪位大神帮帮我啊，万分感谢

解决方案

修改需要反映到include/config/auto.conf
