From 916224c38d2e5a582bba472b9e4b133c12862efa Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Mon, 22 Aug 2016 22:18:21 +0900 Subject: [PATCH] tools: moveconfig: warn loudly if moved option has no entry in Kconfig Currently, the tool gives up moving an option quietly if its entry was not found in Kconfig. If the option is not defined in the config header in the first place, it is no problem (as the Kconfig entry may have been hidden by reasonable "depends on"). However, if the option is defined in the config header, the missing Kconfig entry is a sign of possible behavior change. It is highly recommended to manually check if the option has been moved as expected. In this case, let's add "suspicious" in the log and change the log color (if --color option is given) to make it stand out. This was suggested by Tom in [1].
