- I forked other repository to my own account.
- I cloned this forked repository to my computer. 
- Now i have 2 changed files, ready to commit them (I do not know why). To update (git rebase) my cloned forked repository from origin, I need to have working directory clean. But i haven't, because of this. The only thing come to my mind is to make working directory clean by DISCARD those changes, and then i get my purpose. How to do this? Is there a way to fix this issue? 
Otherwise, I am not able to rebase my local repository.
