From b3476f29d0d76850d89158194dbb1a1b38ce0b79 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Tue, 20 Nov 2018 12:10:14 +0100 Subject: iio: accel: kxcjk1013: Add KIOX010A ACPI Hardware-ID [ Upstream commit 7f6232e69539971cf9eaed07a6c14ab4a2361133 ] Various 2-in-1's use KIOX010A and KIOX020A as HIDs for 2 KXCJ91008 accelerometers. The KIOX010A HID is for the one in the base and the KIOX020A for the accelerometer in the keyboard. Since userspace does not have a way yet to deal with (or ignore) the accelerometer in the keyboard, this commit just adds the KIOX010A HID for now so that display rotation will work.
