Subject: [PATCH] kconfig: change sym_change_count into a boolean flag
sym_change_count has no good reason to be 'int' type.
sym_set_change_count() compares the old and new values after casting
both of them to (bool). I do not see any practical diffrence between
sym_set_change_count(1) and sym_add_change_count(1).
Use the boolean flag, 'conf_changed'.
