commit 4f547472380136718b56064ea5689a61e135f904 upstream.
This appears to fix the error: "xhci_hcd <address>; ERROR Transfer event TRB DMA ptr not part of current TD ep_index 2 comp_code 13" that appear spuriously (or pretty often) when using a r8152 USB3 ethernet adapter with integrated hub.
ASM1042 reports as a 0.96 controller, but appears to behave more like 1.0
