From d7372cdf6938ccea23ec9fc68970702fed9ec3c8 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 19 Jul 2007 01:47:39 -0700 Subject: [PATCH] ACPI: Do not prepare for hibernation in acpi_shutdown Since we are now explicitly calling hibernation_ops->prepare() before hibernation_ops->enter() in hibernation_platform_enter() (defined in kernel/power/disk.c), ACPI should not call acpi_sleep_prepare(ACPI_STATE_S4) from acpi_shutdown().
