[media] tm6000: Fix resource freeing in 'tm6000_prepare_isoc()'
'usb_free_urb(urb)' is a no-op, because urb is known to be NULL.
It is likelly that releasing resources allocated by
'tm6000_alloc_urb_buffers()' just a few lines above is expected here.
This has been spotted by the following coccinelle script:
@@
expression ret, x, e;
identifier f;
@@
* if (x == NULL)
{
... when != x = e;
(
* f(<+...x...+>);
|
* ret = f(<+...x...+>);
)
...
}
