Maybe so, if only because I chose a high value for the max id length to avoid controversy.

Having checkpatch complain about > 80 column lines didn't stop patches before, likely it wouldn't stop patches now. Emitting yet more messages for trivial lines > 80 columns is also against the intent of the commit that changed the line length maximum. commit bdc48fa11e46f867ea4d75fa59ee87a7f48be144 checkpatch/coding-style: deprecate 80-column warning The effect of your patch might as well revert the checkpatch portion of that commit. I think that's not a great idea for the reason in the commit message.
