From 89a8f23fee5ef7545ef6470ef61b61f336df7b49 Mon Sep 17 00:00:00 2001 From: Gabriele Mazzotta Date: Tue, 26 Apr 2022 14:08:27 +0200 Subject: [PATCH] platform/x86: dell-laptop: Add quirk entry for Latitude 7520 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Latitude 7520 supports AC timeouts, but it has no KBD_LED_AC_TOKEN and so changes to stop_timeout appear to have no effect if the laptop is plugged in.
