Subject: [PATCH] ACPI: x86: s2idle: Add a quirk for Lenovo Slim 7 Pro 14ARH7
Git-commit: 888ca9c7955e3969df84f5a1bda2143be9fa365a
Patch-mainline: v6.1-rc1
References: bsc#1206224

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.
