Some Toshiba laptops do not come with the ECO led installed, however, the driver is registering support for it when it should not. This patch makes the toshiba_eco_mode_available function more robust in detecting ECO led capabilities, not registering the led on laptops that do not support it and registering the led when it really does. The ECO led function now returns 0x8e00 (Not Installed) by querying with in[3] = 0, whenever theres no physical LED installed, and returning 0x8300 (Input Data Error) when it is, however, there are some BIOSes that have stub function calls not returning anything and and the LED device was being registered too, hence the change of the default return value from 1 to 0.
