Some people take checkpatch messages altogether too seriously.

from: https://lkml.org/lkml/2015/7/16/568
----------------------------------
The other thing that might help is for people to take
the warnings the script produces less seriously.

Maybe convert:

ERROR -> defect
WARNING -> unstylish
CHECK -> nitpick

or some such

A similar proposal: https://lkml.org/lkml/2016/1/30/175

checkpatch works on patches.
If the #define isn't in the patch scope the script won't know.

Perhaps it's simpler to add some facility to allow lines
with known keywords to exceed $max_line_length similar
to the format strings of logging functions.
