From 5e4856a7dab173777cd4578b4c015af954da4bc6 Mon Sep 17 00:00:00 2001 From: Patrick Pedersen Date: Sat, 15 Jul 2017 14:27:21 +0200 Subject: [PATCH] UBUNTU: SAUCE: (no-up) HID: Add quirk for Lenovo Yoga 910 with ITE Chips BugLink: http://bugs.launchpad.net/bugs/1708120 As with previous generations of this device (see https://patchwork.kernel.org/patch/7887361/), the ITE HID Sensor Hub, responsible for the accelerometer and als sensor, requires a quirk entry. Without the entry, the Sensor Hub can't be accessed and the kernel fails to report any movements. As a result iio-sensor-proxy receives no new data. It shall additionally be noted that the i2c-hid 'sleep' bug (present since kernel ver. 4.3) still affects the driver. This means that the sensor hub will not report any movement, until the device is suspended and resumed.
