Avri Altman 933873852c mmc: core: Don't use close-ended rw for SDUC
The SDUC spec expects CMD22 to get squeezed between CMD23 and the
read/write command, e.g. CMD23->CMD22->CMD18 and CMD23->CMD22->CMD25.
At this early stage of adoption, we want to avoid an amid stream of
fixes & quirks of bogus hw, that tends to apply extra logic specifically
around auto-cmd12 & auto-cmd23.

Let's leave close-ended out for now, and re-consider this should those
cards become ubiquitous, if any.

It also means that BLK_FEAT_FUA will not be used for I/O, but instead we
will rely on BLK_FEAT_WRITE_CACHE.

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 reStructuredText 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.
