Subject: Re: [PATCH 2/3] staging: media: zoran: Code cleanup - else is not
 generally useful after a break or return

Just say concisely what you did in the subject line.  For example, "remove
unneeded else".  The reader can wait to see the message to find out the
details.  "Code cleanup" takes up a lot of space, and doesn't give much
information.
