Note that even though the DMI quirk table name was video_vendor_dmi_table, 5/6 quirks were actually quirks to use the GPU native backlight. These 5 quirks also had a callback in their dmi_system_id entry which disabled the acer-wmi vendor driver; and any DMI match resulted in: acpi_video_set_dmi_backlight_type(acpi_backlight_vendor); which disabled the acpi_video driver, so only the native driver was left. The new entries for these 5/6 devices correctly marks these as needing the native backlight driver. Also note that other changes in this series change the native backlight drivers to no longer unconditionally register their backlight. Instead these drivers now do this check: if (acpi_video_get_backlight_type(false) != acpi_backlight_native) return 0; /* bail */ which without this patch would have broken these 5/6 "special" quirks. Since I had to look at all the commits adding the quirks anyways, to make sure that I understood the code correctly, I've also added links to the various original bugzillas for these quirks to the new entries.
