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.

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
