From c157dfa3e4aea5775389f2f4d53c040bc8813af1 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 13 Jul 2008 22:45:06 +0200 Subject: PCI PM: Fix pci_prepare_to_sleep The recently introduced pci_prepare_to_sleep() needs the following fix, because there are systems which are not power manageable by ACPI (ie. ACPI doesn't provide methods to put the device into low power states and back), but require ACPI hooks to be executed for wake-up to work. Signed-off-by: Rafael J.
