You should use IS_ERR() instead of IS_ERR_OR_NULL(), since functions
of which the return value is being tested return only ERR_PTR() values.
IS_ERR_OR_NULL() suggest NULL values are possible and then constructs
like
        if (IS_ERR_OR_NULL(result))
                return PTR_ERR(result);

are not correct anyway.

OK. I'll use IS_ERR() instead of IS_ERR_OR_NULL()

Thanks, I forgot to mention there is similar issue in patches
5/20 and 6/20.
