Subject: [PATCH] ACPI: video: Add backlight=native DMI quirk for Lenovo ThinkPad X131e (3371 AMD version)
Git-commit: bd5d93df86a7ddf98a2a37e9c3751e3cb334a66c
Patch-mainline: v6.5-rc1
References: git-fixes
Linux defaults to picking the non-working ACPI video backlight interface
on the Lenovo ThinkPad X131e (3371 AMD version).
Add a DMI quirk to pick the working native radeon_bl0 interface instead.
