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. Signed-off-by: Zhang Rui <rui.zhang@intel.com> Signed-off-by: Len Brown <len.brown@intel.com>
