The comedi driver does some wonky stuff if CONFIG_PROC_FS isn't set. It
conditionally defined these functions if it's set to a forward declaration, but
then if it's not set it makes them empty. However, the *real* definitions aren't
protected by the same kind of ifdefs. In case Greg can't reproduce this, here's
a quick-n-dirty patch to do just that.
I think in reality there should be some way to exclude that proc.c file entirely
if CONFIG_PROC_FS is not set, but I'll leave that to the pros. (Whom I am adding
to the CC-list, BTW).

Don't include procfs functions if CONFIG_PROC_FS is not set
