   4 Subject: [PATCH] kbuild: Silence unavoidable dtc overlay warnings
   5
   6 Much effort has been put into finding ways to avoid warnings from dtc
   7 about overlays, usually to do with the presence of #address-cells and
   8 size-cells, but not exclusively so. Since the issues being warned about
   9 are harmless, suppress the warnings to declutter the build output and
  10 to avoid alarming users.
