In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add HAS_IOPORT as dependency for
those drivers using them. For SND_OPL3_LIB this adds its first
dependency so drivers currently selecting it unconditionally need to
depend on it instead.

Both of those are the items to be reverse-selected, so cannot fulfill
the dependency with depends-on.  That is, the items that select those
should have the dependency on HAS_IOPORT instead.

That is, a change like below:

... won't work.  CONFIG_SND_OPL3_LIB is not enabled by itself but only
to be selected.


thanks,

Yes, that makes sense.

Agreed.
