[RFC] [PATCH V2 2/3] ACPI video hotkey: remove invalid events handled by video output devices

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Both ACPI_VIDEO_NOTIFY_SWITCH and ACPI_VIDEO_NOTIFY_PROBE
are valid for video Display Devices only.

ACPI video output devices should not handle these kinds of events.
