This exported function only does a free_irq() for the dio200 legacy and PCI drivers. The ISA driver also calls comedi_legacy_detach() which would also do the free_irq(). Remove the exported function and use comedi_legacy_detach() directly in the legacy driver for the (*detach). Add the free_irq() to the PCI drivers (*detach).
