From 0a28c47b8db8ff74d1bfbc5c5ad0100cea472351 Mon Sep 17 00:00:00 2001 From: Jan Beulich Date: Wed, 30 Jun 2010 13:11:01 +0100 Subject: kconfig: Don't write invisible choice values This makes it so "make oldconfig" really prompts for any choice where options that previously weren't visible just became so. Previously one would have to remember to go over all choice values and check whether some that previously couldn't be selected now can be.
