The patch above isn't fixing any syntax errors, but rather minor cleanup.
The subject should have been "Remove duplicate 'to' in the
flush_dcache_page() comment".
I think that this kind of cleanup patches (typofixes) are best done
as part of **actual** work on the code in question (for example
refactoring or fixing build errors).
