+From 2dc1cdee053846fafc98a819bdad1533ac7c2f04 Mon Sep 17 00:00:00 2001
+From: Hannes Reinecke <[EMAIL PROTECTED]>
+Date: Fri, 19 Oct 2007 09:13:17 +0200
+Subject: [PATCH 1/4] aic7xxx: Add suspend/resume support
+
+The aic7xxx driver already contains fragments for suspend/resume
+support. So we only need to update them to the current interface
+and have full PCI suspend/resume.
+
+Signed-off-by: Hannes Reinecke <[EMAIL PROTECTED]>
