If the response\nslot remains in use after the timeout and after the polled CREQ service\nattempt, the loop starts another full timeout period and can repeat\nforever.\n\nReturn -ENODEV after a timed out wait that still has no response.  The\nexisting caller then marks FIRMWARE_STALL_DETECTED and returns\n-ETIMEDOUT to the command issuer."
