IMO it is not worth to clutter the code with ifdefs just to save some
bytes of binary space, but ok, that's just my two cents.

static struct resource smsc911x_resources[] = {
	{
		.start = LAN9217_BASE_ADDR,
		.end = LAN9217_BASE_ADDR + 0x100,
		.flags = IORESOURCE_MEM,
	},{
		.start = LAN9217_IRQ,
		.end = LAN9217_IRQ,
		.flags = IORESOURCE_IRQ,
	},
};
