From cdcd7162f822a7629a79e11c8490fbeb322bd30e Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Thu, 10 Nov 2016 13:20:05 +0800 Subject: [PATCH] ALSA: hda - add a new condition to check if it is thinkpad 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.
