From e54049d481a9b25f5ae292f671e6aecb6d79f532 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Tue, 23 Aug 2022 13:51:33 -0500 Subject: [PATCH] ACPI: OSI: Remove Linux-HPI-Hybrid-Graphics _OSI string This string was introduced because drivers for NVIDIA hardware didn't handle mux control properly. This was fixed by commit 8e55f99c510f ("drm/i915: Invoke another _DSM to enable MUX on HP Workstation laptops"), so vendors shouldn't be using this string to modify ASL any more.
