From 6ed4c5874f18031f231b069e1da02b1a319bf7c1 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 21 Sep 2022 15:40:53 -0500 Subject: [PATCH] ACPI: x86: s2idle: Add a quirk for Lenovo Slim 7 Pro 14ARH7 Lenovo Slim 7 Pro 14ARH7 has a sporadically non-functional keyboard when resuming from s2idle. This is caused by some missing calls to the EC that don't occur in the AMD codepath but only in the Microsoft codepath. Add the system to the quirk list to force Microsoft codepath.
