Sounds to me we should route this fix to stable.

Looking at Linus' branch:

https://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl.git/commit/?h=fixes&id=ba714a9c1dea85e0bf2899d02dfeb9c70040427c

patch isn't tagged for stable.

Should it be?

It certainly is an improvement of the situation.
