Ayush Sawal fb90a1c85d Crypto/chcr: Calculate src and dst sg lengths separately for dma map
This patch calculates src and dst sg lengths separately for
dma mapping in case of aead operation.

This fixes a panic which occurs due to the accessing of a zero
length sg.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
