V4L/DVB (7108): radio-si470x.c: check-after-use
Adrian used the coverity checker against radio-si470x and found this:
> The Coverity checker spotted the following check-after-use in
> drivers/media/radio/radio-si470x.c:
>
> <-- snip -->
> static void si470x_usb_driver_disconnect(struct usb_interface *intf)
> {
> struct si470x_device *radio = usb_get_intfdata(intf);
>

> flush_scheduled_work();

> usb_set_intfdata(intf, NULL);
> if (radio) { <------------------
> video_unregister_device(radio->videodev);
