Hi Rafael, Here is a series of patches to fix known (and likely also unknown) regressions caused by the backlight-detect refactor landing in 6.1. This builds on top of the earlier Chromebook fix which went upstream through platform-drivers-x86.git/fixes. as such I believe it would be best for this series to go upstream through the pdx86 tree. Can you please give your Ack for merging this through the pdx86 git tree? Regards, Hans Hans de Goede (3): ACPI: video: Improve Chromebook checks ACPI: video: Make acpi_video_backlight_use_native() always return true ACPI: video: Add backlight=native DMI quirk for Dell G15 5515 drivers/acpi/video_detect.c | 41 +++++++++++++++++++++++++++++-------- 1 file changed, 32 insertions(+), 9 deletions(-) -- 2.37.3
