From 082776e4be791736c32baf818e50f501a7f83819 Mon Sep 17 00:00:00 2001 From: Nigel Cunningham Date: Thu, 23 Mar 2006 23:22:16 +1000 Subject: [PATCH] Make libata not powerdown drivers on PM_EVENT_FREEZE. At the moment libata doesn't pass pm_message_t down ata_device_suspend. This causes drives to be powered down when we just want a freeze, causing unnecessary wear and tear. This patch gets pm_message_t passed down so that it can be used to determine whether to power down the drive.
