Subject: [PATCH] Staging: rtl8712: Remove unnecessary cast on void pointer
The conversion from void pointer to any other pointer type is guaranteed
by the C programming language.
The semantic patch used to find this:
@r@
expression x;
void* e;
type T;
identifier f;
@@
(
*((T *)e)
|
((T *)x)[...]
|
((T *)x)->f
|
- (T *)
e
)
