From 9ba16087d9f996a93ab6f4453a52a4b24bc1f25c Mon Sep 17 00:00:00 2001 From: Jan Beulich <jbeulich@novell.com> Date: Wed, 15 Oct 2008 22:01:38 -0700 Subject: [PATCH] Kconfig: eliminate "def_bool n" constructs Using "def_bool n" is pointless, simply using bool here appears more appropriate. Further, retaining such options that don't have a prompt and aren't selected by anything seems also at least questionable.
