From 8743d66979e494c5378563e6b5a32e913380abd8 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Tue, 11 Feb 2025 14:32:01 -0600 Subject: [PATCH] gpiolib: acpi: Add a quirk for Acer Nitro ANV14 Spurious immediate wake up events are reported on Acer Nitro ANV14. GPIO 11 is specified as an edge triggered input and also a wake source but this pin is supposed to be an output pin for an LED, so it's effectively floating. Block the interrupt from getting set up for this GPIO on this device.
