Mengqi Zhang 5a88e29221 mmc: mtk-sd: receive cmd8 data when hs400 tuning fail 
[ Upstream commit 9374ae912d ]

When we use cmd8 as the tuning command in hs400 mode, the command
response sent back by some eMMC devices cannot be correctly sampled
by MTK eMMC controller at some weak sample timing. In this case,
command timeout error may occur. So we must receive the following
data to make sure the next cmd8 send correctly.

README 

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.
