This is a note to let you know that I've just added the patch titled platform/x86: Make dual_accel_detect() KIOX010A + KIOX020A detect more robust to the 5.13-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: platform-x86-make-dual_accel_detect-kiox010a-kiox020a-detect-more-robust.patch and it can be found in the queue-5.13 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. >From 085fc31f81765e061c78cdcab0e5516fd672bff7 Mon Sep 17 00:00:00 2001 From: Hans de Goede <hdegoede@xxxxxxxxxx> Date: Mon, 2 Aug 2021 16:10:00 +0200 Subject: platform/x86: Make dual_accel_detect() KIOX010A + KIOX020A detect more robust From: Hans de Goede <hdegoede@xxxxxxxxxx> commit 085fc31f81765e061c78cdcab0e5516fd672bff7 upstream. 360 degree hinges devices with dual KIOX010A + KIOX020A accelerometers always have both a KIOX010A and a KIOX020A ACPI device (one for each accel). Theoretical some vendor may re-use some DSDT for a non-convertible stripping out just the KIOX020A ACPI device from the DSDT. Check that both ACPI devices are present to make the check more robust.
