From 7c3ad60b3f33d145b75b707c629748e06d7a652d Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Tue, 23 Aug 2022 13:51:32 -0500 Subject: [PATCH] ACPI: OSI: Remove Linux-Lenovo-NV-HDMI-Audio _OSI string This string was introduced because drivers for NVIDIA hardware didn't handle HDMI properly. This was fixed by commit b516ea586d71 ("PCI: Enable NVIDIA HDA controllers"), so vendors shouldn't be using this string to modify ASL any more.
