networking: make skb_pull & friends return void pointers
It seems like a historic accident that these return unsigned char *, and in many places that means casts are required, more often than not. Make these functions return void * and remove all the casts across the tree, adding a (u8 *) cast only where the unsigned char pointer was used directly, all done with the following spatch: @@ expression SKB, LEN; typedef u8; identifier fn = { skb_pull, __skb_pull, skb_pull_inline, __pskb_pull_tail, __pskb_pull, pskb_pull }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_pull, __skb_pull, skb_pull_inline, __pskb_pull_tail, __pskb_pull, pskb_pull }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.
