[Intel-gfx] [PATCH 00/22] Fallback to native backlight

[Akihiko Odaki]

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.
