Subject: Start iterating over menu items from the minimum value, not 0.
X-Git-Tag: v4l-utils-0.8.2~140
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=a59c98e343b960ce1f2520cd2595073c5e695765;p=platform%2Fupstream%2Fv4l-utils.git

Start iterating over menu items from the minimum value, not 0.

More a style issue than anything else. It is slightly more efficient
if the minimum menu index is not 0.
