From 6f36a21e2a77b33eed45159a1556a4dd77422976 Mon Sep 17 00:00:00 2001 From: Phil Elwell Date: Fri, 29 Jan 2021 10:34:11 +0000 Subject: [PATCH] kbuild: Silence unavoidable dtc overlay warnings Much effort has been put into finding ways to avoid warnings from dtc about overlays, usually to do with the presence of #address-cells and size-cells, but not exclusively so. Since the issues being warned about are harmless, suppress the warnings to declutter the build output and to avoid alarming users.
