From 354258011e8e86961f7a72ad154ca8caf0c4c6f7 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 24 May 2011 23:35:55 +0200 Subject: [PATCH] PM / Hibernate: Remove arch_prepare_suspend() All architectures supporting hibernation define arch_prepare_suspend() as an empty function, so remove it.
