Re[2]: [PATCH v2] fix: add XHCI_SPURIOUS_SUCCESS to ASM1042 despite being a V0.96 controller
From: Jens Glathe

Hi there,
I'm a bit at a loss here. This is a three-line change, and I get loads
of warnings regarding "please, no spaces at beginning of lines". I also
got some about proper indentation... what now? Anyway. I have
reformatted the whole section that replaces the three lines, all tab
indents. Script/bot doesn't really like it, but looks proper to me as a
coder.
Anyway, the issue at hand is a bit bigger. I installed mutt and git-mail
on the dev machine, and it actually works. But guess what, when I want
to mail out the patch to the maintainers, it gets rejected by the mailer
daemon (not on my machine, some MTA on the way) because 1und1 (my isp
where the email address I use is registered) has a low reputation and
gets blacklisted. So I go and use the eMClient on my Windows machine and
attach the patch file... I could do an uuencode and copy/paste the text,
maybe next time.
Also, I happen to not understand this patch and patch resend business,
apparrently. I tried to fix all check errors of scripts/checkpatch.pl,
and amended my commit in my branch (apparrently this). So this is still
one commit... and the patch is one patch that should go into an upstream
commit... and that should be it.
To conclude,
- I tried to fix the format
- I can't fix the other MTA (and I won't go out and get employed at
intel or something to have a respectable email address)
- I don't understand this resubmit business.
Can you please help? In the meantime I will re-read "The canonical patch
format" for further insight.
with best regards
Jens Glathe

Hi there,
second try at a patch which was an actual pain with my Lenovo T500 notebook, augmented with an USB3 PCMCIA card that has an ASM1042 chip. Inspired by this email thread: https://markmail.org/thread/7vzqbe7t6du6qsw3
ASM1042 identifies as a 0x96 XHCI host, brings spurious transfer event errors with a r8152 (Realtek 8153a) USB3 enthernet adapter. Additionally setting quirk XHCI_SPURIOUS_SUCCESS seems to resolve this issue in this case.

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.

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 contains warnings and/or errors noticed by the
scripts/checkpatch.pl tool.
- 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
