From c9b6c8f68ee48e1e3dbb53e13316757e2c0b584d Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Tue, 8 Jan 2008 00:10:57 +0100 Subject: ACPI: Print message before calling _PTS Make acpi_sleep_prepare() static and cause it to print a message specifying the ACPI system sleep state to be entered (helpful for debugging the suspend/hibernation code).
