From d431dfb764b145369be820fcdfd50f2159b9bbc2 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Mon, 22 Nov 2021 18:05:30 +0100 Subject: ACPI / x86: Drop PWM2 device on Lenovo Yoga Book from always present table It turns out that there is a WMI object which controls the PWM2 device used for the keyboard backlight and that WMI object also provides some other useful functionality. The upcoming lenovo-yogabook-wmi driver will offer both backlight control and the other functionality, so there no longer is a need to have the lpss-pwm driver binding to PWM2 for backlight control; and this is now actually undesirable because this will cause both the WMI code and the lpss-pwm driver to poke at the same PWM controller. Drop the always-present quirk for the PWM2 ACPI-device, so that the lpss-pwm controller will no longer bind to it. Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
