Lucas Segarra Fernandez d807f0240c crypto: qat - add cnv_errors debugfs file
The Compress and Verify (CnV) feature check and ensures data integrity
in the compression operation. The implementation of CnV keeps a record
of the CnV errors that have occurred since the driver was loaded.

Expose CnV error stats by providing the "cnv_errors" file under
debugfs. This includes the number of errors detected up to now and
the type of the last error. The error count is provided on a per
Acceleration Engine basis and it is reset every time the driver is loaded.

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.
