This patch moves all the option allocations (pnp_mem, pnp_port, etc)
into the pnp_register_{mem,port,irq,dma}_resource() functions.  This
will make it easier to rework the option data structures.

The non-trivial part of this patch is the IRQ handling.  The backends
have to allocate a local pnp_irq_mask_t bitmap, populate it, and pass
a pointer to pnp_register_irq_resource().

for (i = 0; i < 16; i++) (16 instead of 15) it would seem.

And why not simply:

bitmap_zero(map.bits, PNP_IRQ_NR);
bitmap_copy(map.bits, &bits, 16);

That last bit of the comment same for pnpbios_parse_irq_option(). Should be fine, no?

 static __init void pnpbios_parse_port_option(struct pnp_dev *dev,
 					     unsigned char *p, int size,
 					     struct pnp_option *option)
 {
-	struct pnp_port *port;
+	resource_size_t min, max, align, len, flags;

unsigned char flags;

All the rest:
