Subject: [PATCH] ALSA: hda - add a new condition to check if it is thinkpad
Git-commit: 2ecb704a1290edb5e3d53a75529192e7ed2a1a28
Patch-mainline: v4.9-rc6
References: bsc#1099810

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.
