Subject: [PATCH] procfs: Drop cast

This patch does away with cast on void * and the if as it is unnecessary.

The following Coccinelle semantic patch was used for making the change:

@r@
expression x;
void* e;
type T;
identifier f;
@@

(
  *((T *)e)
|
  ((T *)x)[...]
|
  ((T *)x)->f
|
- (T *)
  e
)
