The attached patch simplifies 29df8d8f.  As
the "pnp_xxx" structs are not designed to cope with IORESOURCE_DISABLED, and
hence no code can test for this value, setting this value is actually a "no op"
and can be skipped altogether.  It is sufficient to remove the checks for
"empty" resources and continue processing.

The patch is applied against 3.1.
