This may be a source of many problem in the future.
I advise you to use kbuild.
Try sending me ls -R in a clean tree,
your current Makefile or eventueally the src.
Then I will try to guide you.

The above should not result in the error you describe.
KBUILD_MODNAME is defined to the name of the module
when compiling my_module.mod.c.
Take a look at the output when you use the V=1 option when running make.
If you do not see something like:
$> make -C ~/bk/mars O=~/o M=$PWD V=1
...
gcc -Wp,-MD,/home/sam/bk/external/sam/.sam.o.d -nostdinc -iwithprefix include -D__KERNEL__ -Iinclude -Iinclude2 -I/home/sam/bk/mars/include -I/home/sam/bk/external/sam -Wall -Wstrict-prototypes -Wno-trigraphs -fno-strict-aliasing -fno-common -pipe -msoft-float -mpreferred-stack-boundary=2 -march=pentium3 -I/home/sam/bk/mars/include/asm-i386/mach-default -Iinclude/asm-i386/mach-default -O2 -fomit-frame-pointer -Wdeclaration-after-statement -I/home/sam/bk/mars/ -I /home/sam/bk/external/sam/include -DMODULE -DKBUILD_BASENAME=sam -DKBUILD_MODNAME=sammy -c -o /home/sam/bk/external/sam/sam.o /home/sam/bk/external/sam/sam.c
...
[file is named sam.o, module is named sammy]
Then there is something wrong. You should see -DKBUILD_MODNAME=my_module
