Mark, can you verify that this is not needed with your hardware anymore?
As far as I can see it is still needed. If no config file, no devices
are created and configured. I had planned to remove that code such that
all the different cards supported are still supported. Even though I
only have 2 different types of cards. I Just haven't got to it yet. I
realize "configuration files should not be parsed in the kernel" and I'm
certainly not going to argue that. But the way it is, it allows user
land to define board order and even device node names (additional links
to the actual device). No matter where boards are installed and found by
the kernel, you have persistent naming. I guess all that can be done
with udev (well, sort of anyway).
There are also options in the config file that should be passed in as
module parameters
and I planned to do that part before messing with the config file code.
We also have this "DIGI_EXPANDERS_SUPPORTED" thingy. I have none of
these cards. These cards interrogate the expander to find out how many
ports there are. Then configure accordingly. Should we just remove all
that code and NOT support expanders since we don't currently have the
hardware to test?
I will update from your current git tree and test this week. I've been
swamped lately and unable to do much. I thought I'd be available to do
some more work but things come up as you know.

Mark
