From 969e9afd489514252a680914c6d8b9322c713eb4 Mon Sep 17 00:00:00 2001 From: Pavel Machek Date: Tue, 8 Nov 2005 21:34:30 -0800 Subject: [PATCH] [PATCH] sleep: Fix oops in enter_state If ACPI sleep is not configured, but someone still wants to run swsusp, he'd get oops in enter_state. This is regression since 2.6.14 and this fixes it.
