3.16.40-rc1 review patch. If anyone has any objections, please let me know.
------------------ From: Hui Wang <[email protected]> commit 2ecb704a1290edb5e3d53a75529192e7ed2a1a28 upstream. Latest Thinkpad laptops use the HKEY_HID LEN0268 instead of the LEN0068, as a result neither audio mute led nor mic mute led can work any more. After adding the new HKEY_HID into the is_thinkpad(), both of them works well as before.
