Not only. In the case of fwnode it's a long story behind its corner
case(s) where in the future we might switch from embedded structure to
linked list, for example, in order to address those corner cases.
Should I write a paragraph for that as well?

Thanks.

First of all, even before the 100 characters era the rule had two exceptions:
1) the string literals;
2) the readability over strictness of the 80 characters rule.

While I agree in general with you, in this case I think keeping
strictness makes readability worse.
