From 25bed55753b8cf243406e8837990b55946c5278d Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Fri, 2 Jul 2010 00:12:26 +0200 Subject: [PATCH] ACPI / Sleep: Rework enabling wakeup devices There is no reason why acpi_enable_wakeup_device() should be called with interrupts disabled, because it doesn't access hardware. Thus it is possible to move it next to acpi_enable_wakeup_device_prep() and make the ACPI suspend, hibernate and poweroff code more straightforward. Signed-off-by: Rafael J.
