If anyone has any objections, please let me know. ------------------ From: Krishna Kurapati commit 44ea1ae3cf95db97e10d6ce17527948121f1dd4b upstream. For Gen-1 targets like MSM8996, it is seen that stressing out the controller in host mode results in HC died error: xhci-hcd.12.auto: xHCI host not responding to stop endpoint command xhci-hcd.12.auto: xHCI host controller not responding, assume dead xhci-hcd.12.auto: HC died; cleaning up And at this instant only restarting the host mode fixes it. Disable SuperSpeed instance in park mode for MSM8996 to mitigate this issue.
