From 2d11eae42d52a131f06061015e49dc0f085c5bfc Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Thu, 2 Feb 2023 13:44:49 +0100 Subject: ACPI: video: Fix Lenovo Ideapad Z570 DMI match Multiple Ideapad Z570 variants need acpi_backlight=native to force native use on these pre Windows 8 machines since acpi_video backlight control does not work here. The original DMI quirk matches on a product_name of "102434U" but other variants may have different product_name-s such as e.g. "1024D9U". Move to checking product_version instead as is more or less standard for Lenovo DMI quirks for similar reasons. Signed-off-by: Hans de Goede Signed-off-by: Rafael J.
