11_i2c_hid

#!/bin/sh
# this script takes care of removing the i2c_hid kernel module (touchpad driver) before suspending,
# and loading it again after resuming.
# This avoids spurious messages issued by the driver that interrupt the suspend process:
# i2c_hid i2c-DLL07A0:01: i2c_hid_get_input: incomplete report (83/2)
# HowTo: copy it for example to /etc/pm/sleep.d/11_i2c_hid, then run chmod +x /etc/pm/sleep.d/11_i2c_hid
