I noticed a bunch of "unmet direct dependencies" for xconfig.


I will fix as follows:




diff --git a/scripts/kconfig/expr.c b/scripts/kconfig/expr.c
index 78738ef412de..16f92c4a775a 100644
--- a/scripts/kconfig/expr.c

        e->type = type;
        e->left._initdata = l;
        e->right._initdata = r;
+       e->val_is_valid = false;

        hash_add(expr_hashtable, &e->node, hash);
