Commit1b46c90c8e("crypto: caam - convert top level drivers to libraries") changed entry and exit points behavior for caamalg, caamalg_qi, caamalg_qi2, caamhash, caampkc, caamrng. For example, previously caam_pkc_init() and caam_pkc_exit() were module entry/exit points. This means that if an error would happen in caam_pkc_init(), then caam_pkc_exit() wouldn't have been called. After the mentioned commit, caam_pkc_init() and caam_pkc_exit() are manually called - from jr.c. caam_pkc_exit() is called unconditionally, even if caam_pkc_init() failed. Added a global variable to keep the status of the algorithm registration and free of resources. The exit point of caampkc/caamrng module is executed only if the registration was successful. Therefore we avoid double free of resources in case the algorithm registration failed.

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.
