Other similar impls in the driver carry a TODO[FPRI] comment. Please add one
above this impl:

// TODO[FPRI]: replace with `FromPrimitive`.

Nit: the braces around the single-expression match arm are unnecessary:

    match value {
        bindings::NV2080_CTRL_CMD_CE_GET_FAULT_METHOD_BUFFER_SIZE =>
            Ok(Self::CeGetFaultMethodBufferSize),
        _ => Err(EINVAL),
    }
