Hi Rafael, et. al., As mentioned already in the RFC: """ Here is a second attempt at always registering only a single /sys/class/backlight device per panel. This first round of testing has shown that native works well even on systems so old that the don't have acpi_video backlight control support. This patch series makes native be preferred over vendor, which should avoid the problems seen with the 6.1 changes before the fixes. """ The 2 base patches (last 2 patches of the series now) are unchanged from the RFC. New is a bunch of video_detect DMI quirk updates, 3 small fixes to existing quirks + 2 new quirks. 1 of the new quirks is necessary to avoid a known regression with preferring native over vendor on 1 model, the other DMI quirk is unrelated to the other changes. This series applies on top of the platform-drivers-x86-v6.1-3 tag from: https://git.kernel.org/pub/scm/linux/kernel/git/pdx86/platform-drivers-x86.git/ So either you will need to merge that tag (or merge v6.1-rc5 from Linus) before applying these patches, or I can merge this through my for-next branch which already has these changes. Either way works for me.
