From 86ed4bc83abf530cf2019044b74f89a39dfd6425 Mon Sep 17 00:00:00 2001 From: Bob Moore Date: Thu, 3 May 2012 11:08:19 +0800 Subject: ACPICA: Add support for multiple notify handlers This change adds support to allow multiple notify handlers on Device, ThermalZone, and Processor objects. Also re-worked and restructured the entire notify support code for handler installation, handler removal, notify event queuing, and notify dispatch to handler. Extends and updates original commit 3f0be67("ACPI / ACPICA: Multiple system notify handlers per device") by Rafael Wysocki.
