[ Upstream commitd703c7a994] Don't erase key: If key is erased before the crypto_finalize_.*_request() call, some pending process will run with a key={ 0 }. Moreover if the key is reset at end of request, it breaks xts chaining mode, as for last xts block (in case input len is not a multiple of block) a new AES request is started without calling again set_key().

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.
