From f1575595d15657bd78c139978107deabec5a3959 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 15 Aug 2018 14:59:43 +0900 Subject: [PATCH] kconfig: error out when seeing recursive dependency Originally, recursive dependency was a fatal error for Kconfig because Kconfig cannot compute symbol values in such a situation. Commit d595cea62403 ("kconfig: print more info when we see a recursive dependency") changed it to a warning, which I guess was not intentional. Get it back to an error again. Also, rename the unit test directory "warn_recursive_dep" to "err_recursive_dep" so that it matches to the behavior.
