LG touchscreen (1fd2:8001) stops working after reboot: [ 4.859153] i2c_hid i2c-SAPS2101:00: i2c_hid_get_input: incomplete report (64/66) [ 4.936070] i2c_hid i2c-SAPS2101:00: i2c_hid_get_input: incomplete report (64/66) [ 9.948224] i2c_hid i2c-SAPS2101:00: failed to reset device. The device in question stops working after receives SLEEP, ON, SLEEP commands in a short period. The scenario is like this: - Once the desktop session closes, it also closed the hid device, so the device gets runtime suspended and receives a SLEEP command. - Before calling shutdown callback, it gets runtime resumed and received an ON command. - In the shutdown callback, it receives another SLEEP command. I failed to find a reliable interval between ON/SLEEP commands that can make it work, so let's simply disable runtime PM for the device.
