comedi doesn't like the new irqreturn_t

[Geert Uytterhoeven <geert@linux-m68k.org>]

On m68k:

I suspect a similar problem with drivers/staging/otus, but that one isn't
compiled on m68k due to its dependency on USB.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
