编译linux内核时i2c.h错误以及解决方法

在fedora4上重新编译内核，用自带的/usr/src/kernel/2.6xxxxxx/下死活提示main.o出错，于是重新下载了一个2.6.11.1的内核

编译至此出错

CC drivers/i2c/i2c-core.o
In file included from drivers/i2c/i2c-core.c:29:

make[2]: *** [drivers/i2c/i2c-core.o] 错误 1
make[1]: *** [drivers/i2c] 错误 2
make: *** [drivers] 错误 2

解决方法：

将include/linux/i2c.h中第58，197行内struct i2c_msg msg[]改为struct i2c_msg *msg

linux内核没学到位...哪位高人指点下原因？
