为什么我写的Makefile总是出错？

KERN_DIR = /work/sys/linux-2.6.22.6
all :
        make -C $(KERN_DIR) M='pwd' modules
clean:
        make -C $(KERN_DIR) M='pwd' modules clean
        rm -rf modules.order

obj-m   +=first_diver.o

以上是我写的Makefile
但是我make之后：

book@book-desktop:/work/project/first_drv$ ls
first_diver.c  Makefile
book@book-desktop:/work/project/first_drv$ make
make -C /work/sys/linux-2.6.22.6 M='pwd' modules
make[1]: Entering directory `/work/sys/linux-2.6.22.6'
scripts/Makefile.build:17: /work/sys/linux-2.6.22.6/pwd/Makefile: No such file or directory
make[2]: *** No rule to make target `/work/sys/linux-2.6.22.6/pwd/Makefile'.  Stop.
make[1]: *** [_module_pwd] Error 2
make[1]: Leaving directory `/work/sys/linux-2.6.22.6'
make: *** [all] Error 2
book@book-desktop:/work/project/first_drv$

我检查了C文件的文件名，和makefile内是对的上的，而且我已经配置、编译了内核，也已经生成了uImage，但还是出错，请各位大神帮帮忙


以上是make和make uImage之后的提示信息，都是成功的
