I hit '?' on a new prompt, and saw this: CONFIG_COMEDI_FC: Enable support for shared functions for low-level drivers. This module is not used directly by end-users. Rather, it is used by many other comedi drivers. To compile this driver as a module, choose M here: the module will be called comedi_fc.

It looks like it needs them to enforce proper semantics...)
