Happens to me all the time. What is important is that things are getting
fixed. Personally I don't care that much for the credit.

Note though that your patch subject was a bit misleading, and it may well
be possible that the mips maintainers didn't realize that the fix needed
to be applied to the mips tree. The subject line in the applied patch
describes the change much better as it focuses on the change (what is done),
while the subject line in your patch focuses on the impact (what it fixes).
