Yeah, and the discussion was saying: use 80, unless code readability is
improved by using 100-limit.

You mistake checkpatch with coding style. What checkpatch tells you, is
a suggestion. It's not the coding style. The problem with checkpatch is
that people do not understand "why" it proposes something and they
implement its warnings literally, thus sometimes decreasing code
readability.

Please use wrapping as explained in coding style and deviate to 100
character limit only if it increases the readability.

Best regards,
Krzysztof
