Make mmc core able to use the blk-crypto framework for inline
encryption. This patch introduces a pointer to struct keyslot_manager
to struct mmc_host, and handles setting up the request_queue for
devices using that keyslot_manager appropriately. It also inits struct
mmc_request's inline encryption fields before it's passed to
mmc_host::ops->request.
Users of the core code in host/ (e.g. cqhci.c) should initialize the
keyslot_manager in struct mmc_host appropriately, if they want to
support inline encryption. They should also handle any inline
encryption related work necessary when mmc_host::ops->request is
called.
This patch is only compile tested, as I don't have a device to
actually test these patches. Enable CONFIG_MMC_CRYPTO to test

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
