Yes, of course.
It contains only one line:

obj-$(CONFIG_MY_PROCLISTOUTPUT) += proclistoutput.o

and works with Kconfig

config MY_PROCLISTOUTPUT
    tristate "Display a list of processes"
    default y
    ---help---
     This module prints a list of processes


But I'm sure that the reason is not in my file, because:
- If I put my code in a folder /drivers (and include my Makefile and Kconfig) then everything works perfectly (I can build kernel object and I can built-in my code to the kernel)
- If I put my code in a folder /samples (and include my Makefile and Kconfig) then build-in the code I can't, but with .ko it works fine...

I suppose that the reason in the kernel Makefile. The root Makefile contains this code (http://lxr.free-electrons.com/source/Makefile#L914)

ifdef CONFIG_SAMPLES
         $(Q)$(MAKE) $(build)=samples
endif

where
$(Q) = @
$(build) = -f scripts/Makefile.build obj

and further I lose understanding of the events...

When I allocate my module-code in any other folder (for example, /drivers) it works normally - I can receive .ko and I can make the built-in object.
