[Greg Kroah-Hartman]

4.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Pankaj Gupta <pankaj.gupta@xxxxxxx>

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.
