Giovanni Cabiddu 22ffe829ec crypto: qat - refactor submission logic 
[ Upstream commit af88d3c109 ]

All the algorithms in qat_algs.c and qat_asym_algs.c use the same
pattern to submit messages to the HW queues. Move the submission loop
to a new function, qat_alg_send_message(), and share it between the
symmetric and the asymmetric algorithms.

As part of this rework, since the number of retries before returning an
error is inconsistent between the symmetric and asymmetric
implementations, set it to a value that works for both (i.e. 20, was 10
in qat_algs.c and 100 in qat_asym_algs.c)

In addition fix the return code reported when the HW queues are full.
In that case return -ENOSPC instead of -EBUSY.

Including stable in CC since (1) the error code returned if the HW queues
are full is incorrect and (2) to facilitate the backport of the next fix
"crypto: qat - add backlog mechanism".

README 

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.
