[PATCH] ACPI: video: Add backlight=native DMI quirk for Dell Vostro 15 3535

From: AceLan Kao
Date: Thu Mar 02 2023 - 04:33:15 EST


From: "Chia-Lin Kao (AceLan)" <acelan.kao@xxxxxxxxxxxxx>

Sometimes the system boots up with a acpi_video0 backlight interface
which doesn't work. So add Dell Vostro 15 3535 into the
video_detect_dmi_table to set it to native explicitly.
