This reverts commit 0317e6c0f1dc1ba86b8d9dccc010c5e77b8355fa. Srinivas reported recently touchscreen and touchpad stopped working in Haswell based machine in Linux 4.9-rc series with timeout errors from i2c_designware: [ 16.508013] i2c_designware INT33C3:00: controller timed out [ 16.508302] i2c_hid i2c-MSFT0001:02: failed to change power setting. [ 17.532016] i2c_designware INT33C3:00: controller timed out [ 18.556022] i2c_designware INT33C3:00: controller timed out [ 18.556315] i2c_hid i2c-ATML1000:00: failed to retrieve report from device. I managed to reproduce similar errors on another Haswell based machine where touchscreen initialization fails maybe in every 1/5 - 1/2 boots. Since root cause for these errors is not clear yet and debugging is ongoing it's better to revert this commit as we are near to release.
