Remove this check from the asus-wmi backlight handling: /* Some Asus desktop boards export an acpi-video backlight interface, stop this from showing up */ chassis_type = dmi_get_system_info(DMI_CHASSIS_TYPE); if (chassis_type && !strcmp(chassis_type, "3")) acpi_video_set_dmi_backlight_type(acpi_backlight_vendor); This acpi_video_set_dmi_backlight_type(acpi_backlight_vendor) call must be removed because 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 */ So leaving this in place can break things on laptops with a broken DMI chassis-type, which would have GPU native brightness control before the addition of the acpi_video_get_backlight_type() != native check. Removing this should be ok now, since the ACPI video code has improved heuristics for this itself now (which includes a chassis-type check). Signed-off-by: Hans de Goede <hdegoede@redhat.com> |
