--- Comment #4 from Jonas Platte (jplatte+linux at posteo.de) ---
Workaround works for me too, on a Lenovo Ideapad 530S-14ARR with an AMD Ryzen
2500U. I also set acpi_backlight=vendor to fix the same error message for
backlight:acpi_video1. (No idea why it tries to restore backlight brightness
twice)
