OK.

This is even simpler:

Makefile:

EXTRA_CFLAGS := -I $(obj)/include

module-y := file.o dir/file.o
obj-m := module.o


And then code your C files as usual.
Assumig you have a directory named include.
Include header files like this:
#include "header.h"


So you end up having:

module/file.c
module/Makefile
module/dir/file.c
module/include/header.h

And you use:
make -C kernelsrcdir M=$PWD
to compile your module.

If this does not solve your issue please say so.
