[PATCH 2/6] kconfig: remove unused code for S_DEF_AUTO in conf_read_simple()

From: Masahiro Yamada
Date: Sat Nov 18 2023 - 02:59:23 EST


The 'else' arm here is unreachable in practical use cases.

include/config/auto.conf does not include "# CONFIG_... is not set"
line unless it is manually hacked.
