git create patch with diff

Try a:

git apply --ignore-space-change --ignore-whitespace patch.diff

As mentioned in “git: patch does not apply”, this can be caused by:

• the line endings differing between the local file system and the remote repo.
  User core.eol in .gitattributes file is a good approach (see “git force file encoding on commit”)
• the execution bit (‘x‘).
  That can lead you to set git config core.filemode false, followed by a git reset --hard HEAD (make sure you don’t have uncommitted changes, or they would be lost).
