Hum, I think I would actually prefer something like:

                if (DT_FLAGS_TO_TYPE(flags) == DT_TYPE_IO)
                        rtype = IORESOURCE_IO;
                else if (DT_FLAGS_TO_TYPE(flags) == DT_TYPE_MEM32)
                        rtype = IORESOURCE_MEM;
+               else
+                       continue;

So that we're explicit with the fact that we only care about I/O and
MEM32 resource types.

Agreed, that looks better than my patch as well.

I like it better, too, but we still need the "range += rangesz" part,
so I don't think it will work.  I suppose that could be moved to the
update expression of the "for" loop.  Or, since we don't use "i" in
the loop at all, maybe we could do something like this:

    for (; range < rend; range += rangesz)
