Don't include this line since it prevents git-am from considering the
following lines.

It also seems hotmail base64-encoded your message, which you should try

Please use the same commit-summary prefix as other commits for the
subsystem and driver you're patching (e.g. "USB: serial: cp210x: ")

When possible, try to keep the entries ordered by VID and PID.
