From d67373efece6c4c01148cfcd1b36184b256cf4b5 Mon Sep 17 00:00:00 2001
From: Niall O'Higgins <niallo@cvs.openbsd.org>
Date: Thu, 12 May 2005 14:16:39 +0000
Subject: Add a bzero() after malloc() when allocating component info in
 ccdinit().

This fixes a panic in ccd(4) mirroring where the second component could be
wrongly treated as failed, which leads to uvm_fault in write operation.
