Qianfeng Rong 2ced7045c9 crypto: qat - use kcalloc() in qat_uclo_map_objs_from_mof() 
[ Upstream commit 4c634b6b3c ]

As noted in the kernel documentation [1], open-coded multiplication in
allocator arguments is discouraged because it can lead to integer overflow.

Use kcalloc() to gain built-in overflow protection, making memory
allocation safer when calculating allocation size compared to explicit
multiplication.  Similarly, use size_add() instead of explicit addition
for 'uobj_chunk_num + sobj_chunk_num'.

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 reStructuredText 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.
