None of the lines in this commit are over 80 characters in column
width. Some are exactly 80 characters (like above).

My guess is that you are seeing the diff added text (+ ), which when
you add that to a line which is exactly 80 char in length ends up
being over 80 char in email. If you apply the patch you will see that
they are only 80 chars.

Note that checkpatch also does not complain about any over 80 char
lines in this file.

Sorry if I am misunderstanding what you are trying to tell me. Please
confirm either way.

Thanks
