From f5451582c4e22ce8912aae4950810f3598c9b516 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Tue, 11 Dec 2018 20:01:05 +0900 Subject: kconfig: stop supporting '.' and '/' in unquoted words In my understanding, special characters such as '.' and '/' are supported in unquoted words to use bare file paths in the "source" statement. With the previous commit surrounding all file paths with double quotes, we can drop this.
