commit51fab3d730upstream. 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 Cc: <stable@vger.kernel.org> # v5.1+ Fixes:67c2315def("crypto: caam - add Queue Interface (QI) backend support") Signed-off-by: Horia Geantă <horia.geanta@nxp.com> Reviewed-by: Iuliana Prodan <iuliana.prodan@nxp.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
