 Thank you for the suggestion! Linus Walleij also suggested introducing
a new quirk [1]. Although my main effort is on patching pinctrl-amd.c
without affecting other touchpad together with Hans de Goede [1], I
have spent some time on understanding gpiolib-acpi.c. For now my
conclusion is there is no way to bypass pinctrl-amd by introducing
a new quirk.
