Some Toshiba laptops have "poorly implemented" SCI calls on their
BIOSes and are not checking for sci_{open, close} calls, therefore,
the sci_open function is failing and making some of the supported
features unavailable (kbd backlight, touchpad and illumination).
This patch changes the default return code of the sci_open function
to return one instead of zero, making all those faulty laptops load
all the supported features.
