I'm so sorry for the poor patch description. Is the following description OK?

In the previous iteration of the while loop, "ret" may have been assigned a value of 0, so the error return code -EINVAL may have been incorrectly set to 0.
Also, investigate each case separately as Andy suggessted. If the help function match_int() fails, the error code is returned, which is different from the warning information printed before. If the parsing result token is incorrect, "-EINVAL" is returned and the original warning information is printed.

Please reply below instead of above. See also https://en.wikipedia.org/wiki/Posting_style.

Regarding your question: not logging an error message if user input is rejected is unfriendly to the user. I think it's better to keep the behavior of reporting an error if a match* function fails instead of reporting in the patch description that the behavior has changed.

Thanks,

Bart.
