Subject: [PATCH] ACPI: video: Add backlight=native DMI quirk for Dell Vostro
15 3535
References: bsc#1012628
Patch-mainline: 6.2.10
Git-commit: 89b0411481967a2e8c91190a211a359966cfcf4b
[ 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.
