The backlight part of fujitsu-laptop is only used by laptops which are incapable of using the standard ACPI video interface for handling brightness changes. Conversely, on laptops which are capable of using the latter, no vendor-specific ACPI calls should be made unless explicitly requested by the user. Bail out immediately from acpi_fujitsu_bl_add() unless using the vendor-specific interface was either explicitly requested by the user or automatically selected by the kernel.
