The right way is to use git reset as Peter said. Something like git
reset --hard HEAD. But be aware that this will reset all uncommitted
changes in your index and your working tree. So, if besides my patch
you have other stuff that you care about, take your measures.

Don't be tempted to do sth like git checkout HEAD -- path/to/file as
this will use index to restore your file. And since you used
git-apply, your index is contaminated.

In order to remove untracked files use git clean -f -d.

Feel free to ask, whatever you don't get from the docs.
