Re: [PATCH 5.10 23/49] ACPI: video: Add DMI quirk for GIGABYTE GB-BXBT-2807

Hi!

Something is funny with the From header here. But that's not main thing -- this patch is evil.

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!

Yup, and it looks like this fixes the problem for GIGABYTE GB-BXBT-2807 but re-introduces the problem for Sony VPCEH3U1E.
