I am having a problem with an older patch which is currently in linux-next (20141120) and which might be related to this new patch set. On an Acer C720 if a suspend and resume is performed the touchpad will stop working. If the cyapa driver is reloaded it will begin working again. I performed a bisect and found that the following patch was the cause.
