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 (skb_put, __skb_put and pskb_put) 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_put, __skb_put }; @@ - *(fn(SKB, LEN)) + *(u8 *)fn(SKB, LEN) @@ expression E, SKB, LEN; identifier fn = { skb_put, __skb_put }; type T; @@ - E = ((T *)(fn(SKB, LEN))) + E = fn(SKB, LEN) which actually doesn't cover pskb_put since there are only three users overall. A handful of stragglers were converted manually, notably a macro in drivers/isdn/i4l/isdn_bsdcomp.c and, oddly enough, one of the many instances in net/bluetooth/hci_sock.c. In the former file, I also had to fix one whitespace problem spatch introduced. Signed-off-by: NJohannes Berg <johannes.berg@intel.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Up to now, 'crypto_alloc_shash()' may return a valid pointer, an error pointer or NULL (in case of invalid parameter) Update it to always return an error pointer in case of error. It now returns ERR_PTR(-EINVAL) instead of NULL in case of invalid parameter. This simplifies error handling. Also fix a crash in 'chcr_authenc_setkey()' if 'chcr_alloc_shash()' returns an error pointer and the "goto out" path is taken.
