My previous comment:
"sym_add_change_count(1); seems the convention way
to inform kconfig of some options being updated."
was misleading. Sorry.
conf_write() skips symbol invalidation
when conf_get_change() returns non-zero value.
if (!conf_get_changed())
sym_clear_all_valid();
I do not know why this if-conditional exists here...
Anyway, this patch fixes the issue.
Applied. Thanks.
