AIE4 submits work through a mapped user queue\nand doorbell, not this ioctl path.\n\nReject the submission early with -EOPNOTSUPP when the device provides no\ncmd_submit op, so the shared EXEC ioctl is a clean no-op on such devices.\n\nFound by 0sec automated security-research tooling (https://0sec.ai).",
