[PATCH net-next 1/2] net: Remove casts of void *
From: Joe Perches
Date: Mon Jun 13 2011 - 22:21:52 EST
Unnecessary casts of void * clutter the code.
These are the remainder casts after several specific
patches to remove netdev_priv and dev_priv.
Done via coccinelle script:
$ cat cast_void_pointer.cocci
@@
type T;
T *pt;
void *pv;

- pt = (T *)pv;
+ pt = pv;
