Subjectmedia/radio/radio-si470x.c: check-after-use
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);

del_timer_sync(&radio->timer); <------------------
flush_scheduled_work();

usb_set_intfdata(intf, NULL);
if (radio) { <------------------
video_unregister_device(radio->videodev);
kfree(radio->buffer);
kfree(radio);
}
}
...

<-- snip -->

Either "radio" can be NULL and this case has to be properly handled or
the NULL check is not required.

"Is there not promise of rain?" Ling Tan asked suddenly out
of the darkness. There had been need of rain for many days.
"Only a promise," Lao Er said.
