It is call Yoda condition. As it compare with a constant, the compiler
will throw an error if you write only = instead of != or ==.
But after a quick check, this wasn't needed as compiler warn
builtin/submodule--helper.c:570:2: error: suggest parentheses
around assignment used as truth value [-Werror=parentheses]
And I am not a Yoda condition adept at all. So it will be removed.
