[ Upstream commit f5a6ff923d4a1d639da36228d00e95ff67d417f0 ]
The Sony Vaio VPCY11S1E advertises both native and ACPI video backlight control interfaces, but only the native interface works and the default heuristics end up picking ACPI video on this model.
Add a video_detect_force_native DMI quirk for this.
