Here the spelling of "domains" is correct but in the subject line it's
not (the subject has: doamins)

I found your name in an Android kernel maintainers file with a space
(instead of a dot): Shunzhou Jiang
In Germany a space between the names would be correct - but I can't
tell what's right or wrong for your case.

PS: as a small side-note: when using multiple patches we typically
send a cover-letter.
You can use the following patch-set/series as an example: [0]
It's not critical but it certainly helps identify which patches belong together.


Best regards,
Martin
