This is usb_to_input_id appeared only in later versions of the kernel.

If you want to compile appletouch on older kernels you must  replace the
        usb_to_input_id(dev->udev, &dev->input.id);
line with:
        dev->input.id.bustype = BUS_USB;
        dev->input.id.vendor = id->idVendor;
        dev->input.id.product = id->idProduct;
        dev->input.id.version = 0x0008;

You may also need to change the prototype of atp_suspend from:
    static int atp_suspend(struct usb_interface *iface, pm_message_t
message)
to:
    static int atp_suspend(struct usb_interface *iface, u32 message)
