Subject: [PATCH AUTOSEL 6.2 10/45] ACPI: video: Add backlight=native DMI quirk for Dell Vostro 15 3535

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

[ Upstream commit 89b0411481967a2e8c91190a211a359966cfcf4b ]

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.
