From 86cc558ea52b123d7657e609557d60dc121eedd6 Mon Sep 17 00:00:00 2001 From: Sarah Sharp Date: Fri, 2 Sep 2011 11:05:54 -0700 Subject: [PATCH] xhci: Add software BW checking quirk to Intel PPT xHCI The xHCI host controller in the Intel Panther Point chipset needs to have software check whether new devices will fit in the available bus bandwidth. Activate the software bandwidth checking quirk when we find the right PCI device.
