I would tend to think it should.

This caused a regression for MMP2 platforms that don't use a pinctrl
driver, and none of them do.

On the other hand it went unnoticed since v4.5.

I've seen stable maintainers pick up fixes even when stable@ wasn't
Cc'd. I guess they apply some heuristics and perhaps look at Fixes:
tags to identify bugfixes?
