Giovanni Cabiddu c9ca9756f3 crypto: qat - fix state machines cleanup paths
Commit 1bdc85550a ("crypto: qat - fix concurrency issue when device
state changes") introduced the function adf_dev_down() which wraps the
functions adf_dev_stop() and adf_dev_shutdown().
In a subsequent change, the sequence adf_dev_stop() followed by
adf_dev_shutdown() was then replaced across the driver with just a call
to the function adf_dev_down().

The functions adf_dev_stop() and adf_dev_shutdown() are called in error
paths to stop the accelerator and free up resources and can be called
even if the counterparts adf_dev_init() and adf_dev_start() did not
complete successfully.
However, the implementation of adf_dev_down() prevents the stop/shutdown
sequence if the device is found already down.
For example, if adf_dev_init() fails, the device status is not set as
started and therefore a call to adf_dev_down() won't be calling
adf_dev_shutdown() to undo what adf_dev_init() did.

Do not check if a device is started in adf_dev_down() but do the
equivalent check in adf_sysfs.c when handling a DEV_DOWN command from
the user.

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.
