Hi Angus,

great job with your patch to fix this problem. Please, can you confirm if your patch is merged into CM13.0.
I've installed cm-13.0-20160820-SNAPSHOT-ZNH5YAO0J5 and the touch screen is not working.
Here is the info I could get from my touch screen: http://pastebin.com/DFcYmtiy
Any chance that this patch could me merged into CM13.0 Android M builds?
It also would be great if it could be merged into CM Android N builds so the day they reach stable it keeps compatibility with OEM screens.

Many thanks for your great work.
