Please look at how IORESOURCE_* stuff is defined:
#define IORESOURCE_TYPE_BITS    0x00001f00      /* Resource type */
#define IORESOURCE_IO           0x00000100      /* PCI/ISA I/O ports */
#define IORESOURCE_MEM          0x00000200
#define IORESOURCE_REG          0x00000300      /* Register offsets */
#define IORESOURCE_IRQ          0x00000400
#define IORESOURCE_DMA          0x00000800
#define IORESOURCE_BUS          0x00001000

Notice that it's not an array of bits.

So this should be:
		if ((iter.flags & IORESOURCE_TYPE_BITS) == IORESOURCE_IO) {

And this should be:
		} else if ((iter.flags & IORESOURCE_TYPE_BITS) == IORESOURCE_MEM) {

> +		if (iter.flags & IORESOURCE_IO) {

Same here.

> +		} else if (iter.flags & IORESOURCE_MEM) {

And again here.

ditto.

> +		} else if (flags & IORESOURCE_MEM) {

ditto.
