| Subject: xhci: add restart quirk for Intel Wildcatpoint PCH |
| |
| From: Mathias Nyman <mathias.nyman@linux.intel.com> |
| |
| 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. |
