Subject: [PATCH AUTOSEL 6.1 12/20] ACPI: video: Add backlight=native DMI quirk for HP Pavilion g6-1d80nr
From: Hans de Goede <hdegoede@...hat.com>
[ Upstream commit d77596d432cc4142520af32b5388d512e52e0edb ]
The HP Pavilion g6-1d80nr predates Windows 8, so it defaults to using
acpi_video# for backlight control, but this is non functional on
this model.
Add a DMI quirk to use the native backlight interface which does
work properly.
