media: staging: atomisp: use ARRAY_SIZE
Using the ARRAY_SIZE macro improves the readability of the code. Also,
it is useless to use a variable to store this constant calculated at
compile time.
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))
)
