>From 003cc09f8fc34e7571ebd4a89ea6aa6324a80b54 Mon Sep 17 00:00:00 2001
From: Amit Shah <amit.shah@redhat.com>
Date: Mon, 21 Mar 2011 20:31:45 +0100
Subject: [PATCH 06/19] char: Add a QemuChrHandlers struct to initialise chardev handlers
Instead of passing each handler in the qemu_add_handlers() function,
create a struct of handlers that can be passed to the function instead.
Signed-off-by: Amit Shah <amit.shah@redhat.com>
