... and this is the moment where I append the patch file in hope that
this somehow works.

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.

replaced spaces with tabs
Hi,
This is the friendly patch-bot of Greg Kroah-Hartman. You have sent him
a patch that has triggered this response. He used to manually respond
to these common problems, but in order to save his sanity (he kept
writing the same thing over and over, yet to different people), I was
created. Hopefully you will not take offence and will fix the problem
in your patch and resubmit it so that it can be accepted into the Linux
kernel tree.
You are receiving this message because of the following common error(s)
as indicated below:
- Your patch is malformed (tabs converted to spaces, linewrapped, etc.)
and can not be applied. Please read the file,
Documentation/email-clients.txt in order to fix this.
- Your patch was attached, please place it inline so that it can be
applied directly from the email message itself.
- This looks like a new version of a previously submitted patch, but you
did not list below the --- line any changes from the previous version.
Please read the section entitled "The canonical patch format" in the
kernel file, Documentation/SubmittingPatches for what needs to be done
here to properly describe this.
If you wish to discuss this problem further, or you have questions about
how to resolve this issue, please feel free to respond to this email and
Greg will reply once he has dug out from the pending patches received
from other developers.
thanks,
greg k-h's patch email bot
