    ACPI: video: Add quirk for the Dell Vostro 3350
    
    [ Upstream commit 9249c32ec9197e8d34fe5179c9e31668a205db04 ]
    
    The Dell Vostro 3350 ACPI video-bus device reports spurious
    ACPI_VIDEO_NOTIFY_CYCLE events resulting in spurious KEY_SWITCHVIDEOMODE
    events being reported to userspace (and causing trouble there).
    
    Add a quirk setting the report_key_events mask to
    REPORT_BRIGHTNESS_KEY_EVENTS so that the ACPI_VIDEO_NOTIFY_CYCLE
    events will be ignored, while still reporting brightness up/down
    hotkey-presses to userspace normally.
