Thanks for this explanation. I modified the commit message accordingly and applied the patch to the for-next branch in the following form: commit 92d7ec1d71e351f11ba503369eb78225510cfcc7 Author: Hans Ulli Kroll <ulli.kroll@xxxxxxxxxxxxxx> Date: Mon Mar 5 18:09:10 2018 +0100 leds: Fix wrong dmi_match on PC Engines APU LEDs BIOS on APU board doesn't expose board_name property, and thus we have to rely on the product_name instead.
