by overwriting subdriver.use_iso in .bind or usb_probe [1]

This is ok as we can't be in 2 differents usb_probe (so usbatm.bind) at
same time.



static struct usbatm_driver euatm_drv = {
         .driver_name = "ueagle-atm",
         .owner = THIS_MODULE,
         .bind = eu_bind,
         .atm_start = eu_atm_open,
         .unbind = eu_unbind,
         .atm_stop = eu_atm_stop,
         .heavy_init = eu_heavy,
         .in = EP_BULK_DATA_OUT,.out = EP_BULK_DATA_OUT,

static int eu_probe(struct usb_interface *intf, const struct
usb_device_id *id)
		if (usb_set_interface(usb, USB_INTF_IN, 1) < 0) {
                         eu_err("usb_set_interface failed on iso alt 8\n");
                 else {
                         euatm_drv.in = EP_ISOC_DATA_IN;
                         euatm_drv.use_iso = 1;
                         eu_report("iso mode\n");


The same thing could be done in .bind as usbatm use .in and .use_iso
after .bind().
