Yeah, I've tried it and it solves this issue.

Maybe Should i set source-directory to my emacs-git path in my config?

Or there should be a defcustom instead using source-directory?

Something like this?
#+begin_src emacs-lisp
  (defcustom submit-emacs-patch-src-path source-directory
    "Path to Emacs source directory for submit patch."
    :type 'string)
#+end_src
