Subject: [PATCH 0/3] report: function comments cleanup and the remained
 problem

Hi, 

The following is the result after scaning with my script.

meaning:
count_less: functions with insufficient argument comments.
count_more: functions with redundant argument comments

The patches have cleaned up the "count_more", but except velocity_rx_copy() 
and zd_op_tx(). As I am not sure how to change them precisely. 
They are pointed out with "-->" in the first list.
