The Linux ACPI core locates the ACPI video devices for us and marks them with ACPI_VIDEO_HID. Use that information to locate the video device instead of a half-baked hunt for _BCL. This uncouples the detection of the number of backlight brightness levels on ThinkPads from the ACPI paths in vid_handle. With this change, the driver should be able to always detect whether the ThinkPad uses a 8-level or 16-level brightness scale even on newer models for which the vid_handle paths have not been updated yet. It will skip deactivated devices in the ACPI device tree, which is a change in behaviour. Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Signed-off-by: Matthew Garrett <mjg@redhat.com> |
