Subject: staging: gdm72xx: Remove useless cast on void pointer
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=edb3cc10e03874067c7e86107462a89b54bfdfc9;p=deliverable%2Flinux.git

staging: gdm72xx: Remove useless cast on void pointer

void pointers do not need to be cast to other pointer types.

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
)

Build tested it.
