  The Lenovo Yoga 2 13" models report as "Lenovo Yoga 2" or "Lenovo Yogo
  2 Pro" without the size identifier. Fedora has incorporated their
  version of the patch here:

  https://bugzilla.redhat.com/show_bug.cgi?id=1021036

  This also affects issue where the same information is shown:

  https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1324095

  The above needs to be adjusted to include the line:

  DMI_MATCH(DMI_PRODUCT_VERSION, "Lenovo Yoga 2"),
  DMI_MATCH(DMI_PRODUCT_VERSION, "Lenovo Yogo 2 Pro"),
