Unfortunately this isn't a fix for all Samsung laptops with broken backlight adjustment. The driver assumes by default that acpi_video should be used, and models with broken acpi_video have to be added individually. So this is only going to fix your particular model.
Great! I'll work on getting the changes applied.
