From ad5a796b9e0099754b8ed0f492fbbc000f4668a0 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 6 Jul 2026 14:33:23 +0200 Subject: [PATCH] platform/loongarch: laptop: Stop setting acpi_device_class() The driver populates acpi_device_class() which is never read afterward, so make it stop doing that and drop the symbol defined specifically for this purpose. No intentional functional impact. This will facilitate the removal of device_class from struct acpi_device_pnp in the future. Signed-off-by: Rafael J.
