If anyone has any objections, please let me know. ------------------ From: Krishna Kurapati [ Upstream commit 0046325ae52079b46da13a7f84dd7b2a6f7c38f8 ] For Gen-1 targets like MSM8998, 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 MSM8998 to mitigate this issue.
