Staging: comedi: Remove parentheses around right side assignment

Parentheses are not needed around the right hand side of an assignment.
This patch remove parenthese of such occurences. Issue was detected and
solved using the following coccinelle script:

@rule1@
identifier x, y, z;
expression E1, E2;
@@

(
x = (y == z);
|
x = (E1 == E2);
|
 x =
-(
...
-)
 ;
)
