Masaharu Hayakawa 35cdcd1268 mmc: tmio: Add data timeout error detection
Currently, busy timeout is not checked for data transfer command. But,
if the temperature condition changes, the data cannot be acquired
correctly and timeout may occur. Also, we could reproduce an issue by
using mmc_test driver (e.g. "Correct xfer_size at write (start
failure)"). Therefore, this adds timeout error check.

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.
