OzoneDisplay: Remove unused private member
Missing break statement
patches: Fix script accordingly new pin practices

origin/master now contains the newest fetched tip of Chromium tree and it's not

needs to create a new hacking branch based on 'master', assuming 'master' is
the branch used when last synced (gclient sync).
Gardening: Update to latest version.
