Dmitry Torokhov d0eca5d32b HID: i2c-hid: check if device is there before really probing ... [ Upstream commit b3a81b6c4f ] On many Chromebooks touch devices are multi-sourced; the components are electrically compatible and one can be freely swapped for another without changing the OS image or firmware. To avoid bunch of scary messages when device is not actually present in the system let's try testing basic communication with it and if there is no response terminate probe early with -ENXIO.
