编译驱动时提示implicit declaration of function

我用的内核是linux-2.6.38
Makefile文件如下：
1 ARCH = arm
2 CROSS_COMPILE = arm-linux-
3
4 obj-m := dht11.o
5 KDIR := /opt/FriendlyARM/tiny6410/linux/linux-2.6.38
6 PWD := $(shell pwd)
7 modules:
8 $(MAKE) -C $(KDIR) M=$(PWD) modules
9 clean:
10 $(MAKE) -C $(KDIR) M=$(PWD) clean

包含的头文件有：
1 #include <linux/miscdevice.h>
2 #include <linux/delay.h>
3 #include <asm/irq.h>
4 #include <mach/regs-gpio.h>
5 #include <mach/hardware.h>
6 #include <linux/kernel.h>
7 #include <linux/module.h>
8 #include <linux/init.h>
9 #include <linux/mm.h>
10 #include <linux/fs.h>
11 #include <linux/types.h>
12 #include <linux/delay.h>
13 #include <linux/moduleparam.h>
14 #include <linux/slab.h>
15 #include <linux/errno.h>
16 #include <linux/ioctl.h>
17 #include <linux/cdev.h>
18 #include <linux/string.h>
19 #include <linux/list.h>
20 #include <linux/pci.h>
21 #include <linux/gpio.h>
22 #include <asm/uaccess.h>
23 #include <asm/atomic.h>
24 #include <asm/unistd.h>

请问下怎么解决这问题呢？

是不是内核版本的问题啊，我用的linux-2.6.38,编译别人的驱动（linux-2.6.32）提示一样的问题。
那么2.6.38内核的's3c2410_gpio_getpin' 在哪？

我刚用linux-2.6.28.6版本的还是不行，头文件要怎么改才行呢

有人会吗？求解答啊

这些函数针对s3c24xx系列的, 所以
如果要把这个驱动移植到s3c6410，你需要进行移植，比如s3c2410_gpio_cfgpin改成s3c_gpio_cfgpin

但是我看内核代码的时候是看到s3c2410_gpio_cfgpin函数的。

改成s3c_gpio_cfgpin还是一样。是编译的时候出现同样的问题，
