** Description changed: Driver update in Kernel 4.2 causes severe usability issues with Cypress touchpad (cyapa) used on Acer C7x0 chromebooks. The driver in question is ignoring events during entering/leaving idle status which from user standpoint seems like touchpad is not reacting to actions performed after touchpad is not used for more then 2 seconds. The bug was partially fixed in 4.3 and additional fix was pushed to upcoming 4.5. After direct communication with driver maintainer, we came up with 2 patches fixing the problem. Since 4.2 is EOL now, the patches cannot be pushed into upstream therefor are posted here. First patch is a backport of driver from 4.3 to 4.2 and the second patch is additional fix that should be applied on 4.3/4.4.
