Function aead_ccm_validate_input is local to the source and does not
need to be in global scope, so make it static.

4df864c1d9 networking: make skb_put & 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 (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.

72a56ca97d crypto: chcr - Fix txq ids.
The patch fixes a critical issue to map txqid with flows on the hardware appropriately,
if tx queues created are more than flows configured then  txqid shall map within
the range of hardware flows configured. This ensure that un-mapped txqid does not remain un-handled.
The patch also segregated the rxqid and txqid for clarity.

e29abda591 crypto: chcr - Increase priority of AEAD algos.
templates(gcm,ccm etc) inherit priority value of driver to
calculate its priority. In some cases template priority becomes
 more than driver priority for same algo.
Without this patch we will not be able to use driver authenc algos. It will
be good if it pushed in stable kernel.
