From 7708e1c341a92d6f6c5c987059b84fbef98da205 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 20 Feb 2018 20:40:29 +0900 Subject: [PATCH] kconfig: Don't leak choice names during parsing The named choice is not used in the kernel tree, but if it were used, it would not be freed. The intention of the named choice can be seen in the log of commit a9b06a0aa23c ("kconfig: add named choice group").
