ACPI: video: Drop "Samsung X360" acpi_backlight=native quirk
acpi_backlight=native is the default for the "Samsung X360", but as the comment explains the quirk was still necessary because even briefly registering the acpi_video0 backlight; and then unregistering it once the native driver showed up, was leading to issues. After the "ACPI: video: Make backlight class device registration a separate step" patch from earlier in this patch-series, we no longer briefly register the acpi_video0 backlight on systems where the native driver should be used. So this is no longer an issue an the quirk is no longer needed. Acked-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com>
