From 38dbd6892080c93ccd24fbfa46ed5d9bdb7d9e99 Mon Sep 17 00:00:00 2001 From: Kane Chen Date: Mon, 8 Apr 2019 22:02:37 +0800 Subject: mb/google/octopus: Disable WLAN prior the entry of S5 ODM reported issues that some systems can't be shutdown to S5 very occasionally. ODM found issue is gone if they remove the WLAN card. So, this change to disable WLAN before system enters S5. This change is validated by ODM and it does help issue.
