media: usbtv: fix control-message timeouts commit 536f561d871c5781bc33d26d415685211b94032e upstream. The driver was issuing synchronous uninterruptible control requests without using a timeout. This could lead to the driver hanging on various user requests due to a malfunctioning (or malicious) device until the device is physically disconnected. The USB upper limit of five seconds per request should be more than enough.
