My fault. I forgot to handle some pre-compilation constants when the drivers
are compiled as modules.
I will update my git repository; meanwhile, you can statically link all the
comedi drivers into the kernel. That is a temporary solution until the fix is
available.

Another bug of mine. The EXPORT_SYMBOL was missing.
Once more, with a kernel in which the drivers are statically included, you
won't face this issue anymore.
