First - posting to linux-kbuild will liekly get you more attention.
The old list at sourceforge is no longer active.

The kbuild philosofy is that you specify all .o files.
Considering the many many hours invested writing a single .c file,
then the effort it is to add it to the kbuild file is minimal.

What you fail to realise is that current directory is the root
of the kernel source when you build your module.
Try something like this:
OBJS := $(patsubst %.c, %.o,$(notdir $(wildcard $(src)/*.c)))
$(wildcard $(src)/*.c) will find all .c files in the directory where you module
reside
$(notdir ...) remove the path component.
Try to look at the resulting OBJS like this:
$(warning OBJS=$(OBJS))
Note - I used ":=" above. I always avoid using "=" unless strictly required.
