Because only half of them use IrDA specific struct fields
directly, thus need to be ifdef'd explicitely.
Like I wrote before, we could replace all the
if (USE_IRDA(x)) ...
with some
#ifdef CONFIG_IRDA
if (x->use_irda) ...
but that way we would have more ifdef's around.
A matter of taste, I'ld say. If you vote for the
latter, we can adjust the patch accordingly, of
course.
