The original DMI quirk matches on a product_name of "102434U" but other variants may have different product_name-s such as e.g. "1024D9U". Move to checking product_version instead as is more or less standard for Lenovo DMI quirks for similar reasons. Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
