Subject: [PATCH AUTOSEL 6.1 09/22] ACPI: video: Change GIGABYTE GB-BXBT-2807 quirk to force_none

From: Hans de Goede <hdegoede@...hat.com>

[ Upstream commit 9f7dd272ff9338f1f43c7a837d5a7ee67811d552 ]

The GIGABYTE GB-BXBT-2807 DMI quirk was added by
commit 25417185e9b5 ("ACPI: video: Add DMI quirk for GIGABYTE
GB-BXBT-2807") which says the following in its commit message:

"The GIGABYTE GB-BXBT-2807 is a mini-PC which uses off the shelf
components, like an Intel GPU which is meant for mobile systems.
As such, it, by default, has a backlight controller exposed.

Unfortunately, the backlight controller only confuses userspace, which
sees the existence of a backlight device node and has the unrealistic
belief that there is actually a backlight there!

Add a DMI quirk to force the backlight off on this system."

So in essence this quirk was using a video_detect_force_vendor quirk
to disable backlight control. Now a days we have a specific "none"
backlight type for this. Change the quirk to video_detect_force_none
and group it together with the other force_none quirks.
