| Subject: [PATCH] Kconfig: Add KCONFIG_STRICT mode |
| |
| This is basically a -Werror mode for Kconfig. When exporting |
| KCONFIG_STRICT in the Makefile, warnings in Kconfig will produce |
| errors instead. |
| |
| This will make it easier to spot unclean Kconfig files, settings |
| and dependencies. |
