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.

Cc: <stable@vger.kernel.org> Signed-off-by: Hui Wang <hui.wang@canonical.com> --- And the fix for thinkpad_acpi.c already sent out, and got ACK, please refer to: https://sourceforge.net/p/ibm-acpi/mailman/message/35478616/

Acctually we don't need to wait thinkpad_acpi.c to be patched first, since no matter the thinkpad_acpi.c merge that patch or not, the led control function is always provided by thinkpad_acpi.c, the new HKEY_ID only affects the automatic insmod for thinkpad_acpi.ko.

Thanks, applied now. Takashi
