This broke touchscreen and trackpad: i2c_designware AMDI0010:00: controller timed out i2c_designware AMDI0010:03: controller timed out i2c_hid_acpi i2c-MSFT0001:00: failed to reset device: -61 i2c_designware AMDI0010:03: controller timed out ... i2c_hid_acpi i2c-MSFT0001:00: can't add hid device: -61 i2c_hid_acpi: probe of i2c-MSFT0001:00 failed with error -61 White-list this specific model in the override_table. For this to work, the ZEN test needs to be put below the table walk.
