From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently variable num_segments is being assigned but never actually
used. Fix this actually using it in the for-loop. Also clean up the
code a little by assigning num_segments at declaration time.
Cleans up clang warning: Value stored to 'num_segments' is never read
