From a1eb96a2f635cdb8f626f4074dae2ba5a6fce1e8 Mon Sep 17 00:00:00 2001 From: Zhang Rui Date: Mon, 20 Aug 2007 18:23:51 +0800 Subject: [PATCH] ACPI video hotkey: remove invalid events handler for video output devices Both ACPI_VIDEO_NOTIFY_SWITCH and ACPI_VIDEO_NOTIFY_PROBE are valid for video bus devices only. Actually ACPI video output device should never be notified for a output device switch/probe. ACPI bus devices notify handler already has the code to handle these kinds of events.
