From a69982c37cd0586e6832268155349301b87f2e35 Mon Sep 17 00:00:00 2001 From: Werner Sembach Date: Wed, 15 Feb 2023 15:39:41 +0100 Subject: gpiolib: acpi: Add a ignore wakeup quirk for Clevo NH5xAx The commit 1796f808e4bb ("HID: i2c-hid: acpi: Stop setting wakeup_capable") changed the policy such that I2C touchpads may be able to wake up the system by default if the system is configured as such. However for some devices there is a bug, that is causing the touchpad to instantly wake up the device again once it gets deactivated. The root cause is still under investigation (see Link tag). To workaround this problem for the time being, introduce a quirk for this model that will prevent the wakeup capability for being set for GPIO 16.
