From 8d37f20173a2760718bb02b58bafc5a7cac93d67 Mon Sep 17 00:00:00 2001 From: Mateo Borda Date: Sun, 20 Sep 2026 14:39:04 -0300 Subject: [PATCH] gpiolib: acpi: Add quirk for Lenovo IdeaPad Slim 3 15ABR8 On the Lenovo IdeaPad Slim 3 15ABR8 (82XM), the touchscreen (GTCH7503:00) GPIO interrupt on pin 10 is armed as a wake source. As soon as the system enters s2idle suspend the interrupt fires, causing an immediate spurious resume, so suspend is unusable. Disabling wakeup for the device via sysfs or booting with gpiolib_acpi.ignore_wake=GTCH7503:00@10 avoids the problem, so add a DMI quirk that ignores wakeup on that pin.
