[RFC][PATCH 7/7] ACPI: Print message before calling _PTS
From: Rafael J. Wysocki <hidden>
Date: 2008-01-05 22:58:07
From: Rafael J. Wysocki <redacted> 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).
