From bde40aa4b0b7318fd6c76ea29fc918cbcee6747a Mon Sep 17 00:00:00 2001 From: Mathias Nyman Date: Thu, 20 Oct 2016 18:09:18 +0300 Subject: [PATCH] xhci: add restart quirk for Intel Wildcatpoint PCH commit 4c39135aa412d2f1381e43802523da110ca7855c upstream. xHC in Wildcatpoint-LP PCH is similar to LynxPoint-LP and need the same quirks to prevent machines from spurious restart while shutting them down.
