3.2.70-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Hans de Goede <hdego...@redhat.com>
commit 5f0ee9d17aae628b22be86966471db65be21f262 upstream.
Make the check to skip the rate check more lax, so that it applies
to all hw_version 4 models.
This fixes the touchpad not being detected properly on Asus PU551LA
laptops.
