Comment # 3 on bug 998440 from Takashi Iwai

OK, then could you check whether /sys/bus/acpi/devices/INT33FF:00 is present on
your system.  If yes, we can test it and add the pinctrl-cherryview driver
depending on it.

The attached below is a dracut module script.  Make a directory, e.g.
  /usr/lib/dracut/modules.d/90cherryview
and put the script to /usr/lib/dracut/modules/90cherryview/module-setup.sh.

  # mkdir -p /usr/lib/dracut/modules.d/90cherryview
  # install -c -m 0755 module-setup.sh /usr/lib/dracut/modules.d/90cherryview/

And try to rebuild initrd without extra options.
