If a machine reports a RF Button in the communication button device bitmap, we need to remove it before calling Get Device Status otherwise it will return the "Undefined device" (0xE2) error code. Although this may be a BIOS bug, we don't really need to get or set the RF Button status. The status indicator LED embedded in the button is controlled by firmware logic, depending on the status of the wireless radios present on the machine (WiFi || WWAN). This commit fixes the wireless status indicator LED on the Acer TravelMate P648-G2-MG, and cleans the following message from the kernel log: "Get Current Device Status failed: 0xe2 - 0x0".
