The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

Subject: xhci: Add reset resume quirk for AMD xhci controller.

One of AMD xhci controller require reset on resume. Occasionally AMD xhci controller does not respond to Stop endpoint command.
Once the issue happens controller goes into bad state and in that case controller needs to be reset.
