Adding a new warning flag to W=1 is always safe without doing any compile test. With this series, it would not be true any more because a new warning in W=1 would potentially break riscv/samsung platforms. Linus requires a clean build (i.e. zero warning) when W= option is not given. > Rob Herring (4): > kbuild: Move dtc graph_child_address warning to W=2 > kbuild: Allow arch/platform override of dtc warning level > riscv: dts: Always enable extra W=1 warnings > arm/arm64: dts: samsung: Always enable extra W=1 warnings > > arch/arm/boot/dts/samsung/Makefile | 3 +++ > arch/arm64/boot/dts/exynos/Makefile | 3 +++ > arch/riscv/boot/dts/Makefile | 3 +++ > scripts/Makefile.lib | 16 +++++++++------- > 4 files changed, 18 insertions(+), 7 deletions(-) > --- > base-commit: b85ea95d086471afb4ad062012a4d73cd328fa86 > change-id: 20231122-dtc-warnings-968ff83a86ed > > Best regards, > -- > Rob Herring <robh@xxxxxxxxxx> > -- Best Regards Masahiro Yamada
