Subject: [PATCH] Input TP: Modify the TP in the wake of the problem does not
respond
In the process of repeated sleep and wake up ,sometime TP firmware will not be
able to respond to the AP's TP driver. So it should be in the wake up
function to do abnormal detection. When the TP exception occurs, the TP
driver reset TP firmware.
