Aleksander Jan Bajkowski 0ceeadc7b5 crypto: inside-secure/eip93 - unregister only available algorithm
EIP93 has an options register. This register indicates which crypto
algorithms are implemented in silicon. Supported algorithms are
registered on this basis. Unregister algorithms on the same basis.
Currently, all algorithms are unregistered, even those not supported
by HW. This results in panic on platforms that don't have all options
implemented in silicon.

Linux kernel
============

The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.

Quick Start
-----------

* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/

Essential Documentation
-----------------------

All users should be familiar with:

* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING

Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
