From c1af28f23ab24eac6ef8aeaaaaa74ec151648890 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 31 Dec 2025 09:32:16 -0500 Subject: [PATCH] gpiolib: acpi: Add a quirk for Acer Nitro V15 [ Upstream commit 9ab29ed505557bd106e292184fa4917955eb8e6e ] It is reported that on Acer Nitro V15 suspend only works properly if the keyboard backlight is turned off. In looking through the issue Acer Nitro V15 has a GPIO (#8) specified in _AEI but it has no matching notify device in _EVT. The values for GPIO #8 change as keyboard backlight is turned on and off. This makes it seem that GPIO #8 is actually supposed to be solely for keyboard backlight. Turning off the interrupt for this GPIO fixes the issue. Add a quirk that does just that.
