Topstar U931 laptops provide a LED synced with the WLAN adapter hard-blocking state. Unfortunately, some models seem to be defective, making impossible to hard-block the adapter with the WLAN switch and thus the LED is useless. An ACPI method is available to programmatically control this switch and it indirectly allows to control the LED. This commit registers the LED within the corresponding subsystem, making possible for instance to use an rfkill-based trigger to synchronize the LED with the device state. This workaround is enabled automatically for Topstar U931/RVP7 laptops based on a DMI check.
