It seems I didn't pay attention to this Makefile the first time I looked
at this series. And actually reading it I noticed that
industrialio-configfs.o can only be part of the industrial.ko module,
can't it? So this Makefile doesn't allow to build a separate
industrialio-configfs.ko module, right? If so, my previous review, in
which I claimed to spot a nit, was a waste of our time.
Because I now experienced that if this gets build with CONFIG_IIO=m and
CONFIG_IIO_CONFIGFS=y one gets:
$ make -C ../.. CONFIG_IIO_CONFIGFS=y M=$PWD industrialio.ko
make: Entering directory `[...]'

(I didn't yet test other configurations.)
So before I waste even more of your time: were you trying to make
configfs support a part of the industrialio module or were you trying to
make configfs support available as a separate module?
Thanks,
