dereferencing uninitialized variable in anysee_probe()

[Dan Carpenter <error27@gmail.com>]

Hi I'm going through some smatch stuff and I had a question.

drivers/media/dvb/dvb-usb/anysee.c +482 anysee_probe(30)
	warn: variable dereferenced before check 'd'

   466          ret = dvb_usb_device_init(intf, &anysee_properties, THIS_MODULE, &d,
   467                  adapter_nr);

	If we're in a cold state then dvb_usb_device_init() can return
	zero but d is uninitialized here.

   468          if (ret)
   469                  return ret;
   470
   471          alt = usb_altnum_to_altsetting(intf, 0);
   472          if (alt == NULL) {
   473                  deb_info("%s: no alt found!\n", __func__);
   474                  return -ENODEV;
   475          }
   476
   477          ret = usb_set_interface(d->udev, alt->desc.bInterfaceNumber,
                                        ^^^^^^^
	That would lead to an oops here.

   478                  alt->desc.bAlternateSetting);

I'm not sure how to fix this.
