This takes care of the "make dtbs" case (or just "make" case), but not when you build a specific target. ARM: dts: remove stale dtb files from arch/arm/boot This will result in stale dtb files being removed from arch/arm/boot, which can cause confusion when someone goes from an older kernel version to a newer one without doing make clean on the old version (or git clean -f -d -x).
