[PATCH 3/3] staging: iio: light: Remove useless type conversion

[simran singhal <singhalsimran0@gmail.com>]

Some type conversions like casting a pointer to a pointer of same type,
casting to the original type using addressof(&) operator etc. are not
needed. Therefore, remove them. Done using coccinelle:

@@
type t;
t *p;
t a;
@@
(
- (t)(a)
+ a
|
- (t *)(p)
+ p
|
- (t *)(&a)
+ &a
)
