Commit 2600bfa3df99 ("ACPI: video: Add acpi_video_backlight_use_native() helper") and following commits made native backlight unavailable if CONFIG_ACPI_VIDEO is set and the backlight feature of ACPI video is unavailable, which broke the backlight functionality on Lenovo ThinkPad C13 Yoga Chromebook. Allow to fall back to native backlight in such cases.
