我根据友善提供的led.c的驱动代码自己弄了个驱动代码然后再宿主机上编译不成功啊，想了狠久都不知道为什么，具体看下面编译出现的问题.

我明明已经定义了static unsigned long led_table [] = {
S3C2410_GPB5,
S3C2410_GPB6,
S3C2410_GPB7,
S3C2410_GPB8,
};
static unsigned int led_cfg_table [] = {
S3C2410_GPIO_OUTP,
S3C2410_GPIO_OUTP,
S3C2410_GPIO_OUTP,
S3C2410_GPIO_OUTP,
};
友善提供的源码能编译通过，不会出现什么问题，怪就怪在这里，我的代码跟友善提供的差不多，请看下面友善的代码就知道
static unsigned long led_table [] = {
S3C2410_GPB(5),
S3C2410_GPB(6),
S3C2410_GPB(7),
S3C2410_GPB(8),
};
static unsigned int led_cfg_table [] = {
S3C2410_GPIO_OUTPUT,
S3C2410_GPIO_OUTPUT,
S3C2410_GPIO_OUTPUT,
S3C2410_GPIO_OUTPUT,
};
看到了什么区别吧，只是S3C2410_GPB(5),S3C2410_GPB(6),S3C2410_GPB(7),S3C2410_GPB(8),多了个括号而已，他的就能通过而我的不能，我想知道为什么，请斑竹帮忙啊
