static struct ucb1400_pdata pdata = {
	.irq	= IRQ_GPIO(123),
};

static struct platform_device ucb1400_core = {
        .name   = "ucb1400_core",
        .id     = -1,
	.dev	= {
		.platform_data = &pdata,
	},
};

init() {
	platform_device_register(&ucb1400_core);
}

Like this ?

btw. you don't have to pass pdata at all ... the logic for auto-detecting IRQ is 
still there and is active if no pdata are supplied.
