It is useless to re-invent the ARRAY_SIZE macro so let's use it instead
of DATA_CNT.
Found with Coccinelle with the following semantic patch:
@r depends on (org || report)@
type T;
T[] E;
position p;
@@
(
(sizeof(E)@p /sizeof(*E))
|
(sizeof(E)@p /sizeof(E[...]))
|
(sizeof(E)@p /sizeof(T))
)

Changes since v1:
- keep DATA_CNT as suggested by Steven Rostedt
