You would like to omit a duplicate #include directive, don't you?
Will a corresponding refinement become helpful for the summary phrase?

I don't think this fixes that commit -- `stdarg.h` was not there back then.

Instead, this commit

    be06b53d3af0 ("lib/vsprintf: include stdarg.h from sprintf.h to
provide va_list")

also added the line, and I assume Stephen only needs to drop one of
the lines in this merge resolution next time:

    3f413b9a3770 ("Merge branch 'next' of
https://git.kernel.org/pub/scm/linux/kernel/git/dtor/input.git")

Thanks!

Cheers,
Miguel

Thank you for your feedback. Do I need to submit the v2 version without 
fixes？

You're welcome!

No, I don't think there is a need for a patch for this, since the
issue was in a test merge, not in any particular branch or patch, as
far as I can see. So I assume Stephen will simply fix at merge
tomorrow.

However, if this slips and lands e.g. in Linus' tree, then yes, a
patch would be needed. Maintainers may mention it to Linus to try to
avoid the same issue again in the "real" merge into mainline.

I hope that helps!

Cheers,
Miguel
