... and I spotted my nonsense just as I hit send.

You could do that ^^.  But you'd need to rename the 'inb' op  like:

struct port_io_ops {
	u8 (*f_inb)(u16 port);
	...
};

so that you do:

	#define inb(x) pio_ops.f_inb(x)

But, remember when I said I hate playing #define tricks? ;)  This is one
reason why.
