static struct ucb1400_pdata pdata =3D {
	.irq	=3D IRQ_GPIO(123),
};

static struct platform_device ucb1400_core =3D {
        .name   =3D "ucb1400_core",
        .id     =3D -1,
	.dev	=3D {
		.platform_data =3D &pdata,
	},
};

init() {
	platform_device_register(&ucb1400_core);
}

Like this ?

btw. you don't have to pass pdata at all ... the logic for auto-detecti=
ng IRQ is=20
still there and is active if no pdata are supplied.
