ERN handler calls the caam/qi frontend "done" callback with a status
of -EIO. This is incorrect, since the callback expects a status value
meaningful for the crypto engine - hence the cryptic messages
like the one below:
platform caam_qi: 15: unknown error source
Fix this by providing the callback with:
-the status returned by the crypto engine (fd[status]) in case
it contains an error, OR
-a QI "No error" code otherwise; this will trigger the message:
platform caam_qi: 50000000: Queue Manager Interface: No error
which is fine, since QMan driver provides details about the cause of
failure

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.
