'git am' complains:
error: git diff header lacks filename information when removing 1
leading pathname component.
So I guess probably you don't need to include these email headers in the
changelog/commit message? I'm not sure, but you can take a look at
relevant docs for this.
Also, instead, please write some meaningful info in the commit message,
see:
https://docs.kernel.org/translations/zh_CN/how-to.html#id13
Thanks.

Thanks for the effort, but sadly, "no attachments" is a better practice.
;-)
See:
https://docs.kernel.org/process/submitting-patches.html#no-mime-no-links-no-compression-no-attachments-just-plain-text
Maybe you can try git-send-email later.
Anyway, I manually saved the patch and git am -3 works while git am does
not.

Yeah, I think this one looks good, though.
Thanks.

Subject: [PATCH] docs/zh_CN: add Chinese translation for usb/ohci.rst
Translate Documentation/usb/ohci.rst into Chinese Simplified.
The translation covers OHCI driver overview, hardware protocol
differences (OHCI vs UHCI), improvements since 2.4 kernel,
queueable interrupt transfers, and non-PCI support.
