Subject: [PATCH] fix: add XHCI_SPURIOUS_SUCCESS to ASM1042 despite being a
 V0.96 controller

only if it reports as a V0.96 XHCI controller. Appears to fix the errors
"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.

I can't take attachments, sorry.  Try using 'git send-email' to get this
to work properly.  This guide might help you out with that:
	https://git-send-email.io/

Also look at your subject line and try to match it up with how other
commits for this driver/file are done, it needs to be tweaked a bit.

thanks,
