Please sort function local variables declaration in a reverse christmas
tree order:
<type A> longest_variable_name;
<type B> shorter_var_name;
<type C> even_shorter;
<type D> i;

Err, but this has functional changes: the !e->enable_per_layer_report
case sets only the e->label and the else branch only does increment
->ce_count.
Your change gets ->ce_count incremented in both cases.
Why?
