    Subject[PATCH 4.4 154/230] crypto: caam - fixed handling of sg list
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Pankaj Gupta <pankaj.gupta@nxp.com>

    commit 42e95d1f10dcf8b18b1d7f52f7068985b3dc5b79 upstream.

    when the source sg contains more than 1 fragment and
    destination sg contains 1 fragment, the caam driver
    mishandle the buffers to be sent to caam.

    Fixes: f2147b88b2b1 ("crypto: caam - Convert GCM to new AEAD interface")
