From bfef491df67022c56aab3b831044f8d259f9441f Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 26 Jan 2024 22:30:10 +0900 Subject: kconfig: initialize sym->curr.tri to 'no' for all symbol types again Geert Uytterhoeven reported that commit 4e244c10eab3 ("kconfig: remove unneeded symbol_empty variable") changed the default value of CONFIG_LOG_CPU_MAX_BUF_SHIFT from 12 to 0. As it turned out, this is an undefined behavior because sym_calc_value() stopped setting the sym->curr.tri field for 'int', 'hex', and 'string' symbols. This commit restores the original behavior, where 'int', 'hex', 'string' symbols are interpreted as false if used in boolean contexts. CONFIG_LOG_CPU_MAX_BUF_SHIFT will default to 12 again, irrespective of CONFIG_BASE_SMALL. Presumably, this is not the intended behavior, as already reported [1], but this is another issue that should be addressed by a separate patch.
