Subject: Re: [PATCH] pinctrl: tigerlake: Add Alder Lake-P documentation

Someone erroneously marked the bug as CLOSED INVALID, while only the
proposed resolution was INVALID and not the bug itself.

This patch solves the issue because it informs the user on the correct
driver to choose for Alder Lake-P.
