From af6c23be63d14860c8c1f0d9fcbc020f7c11d84d Mon Sep 17 00:00:00 2001
From: Stefan Reinauer <reinauer@chromium.org>
Date: Thu, 20 Aug 2015 11:19:34 -0700
Subject: [PATCH] kconfig: Allow KCONFIG_STRICT outside of confdata.c
To catch dependency errors in symbol.c (such as the ones
fixed by I51b4ee326f082c6a656a813ee5772e9c34f5c343) we need
to check for global kconfig warnings before saving config
files.
This patch will produce errors for wrong dependencies and
add catching of errors to conf, nconf and mconf. Sorry,
gconf users, you will have to wait.
