From f99648b1aff8b6158333a06c50d627be3c243a32 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Tue, 14 Feb 2012 18:43:03 +0800 Subject: ACPICA: Distill multiple sleep method functions to a single function Adds acpi_hw_execute_sleep_method to handle the various sleep methods such as _GTS, _BFS, _WAK, and _SST. Removes the specialized functions previously used for each of these methods.
