Wolfram Sang 97a7d87e96 mmc: core: add a 'doing_init_tune' flag and a 'mmc_doing_tune' helper
Our driver needs to know when tuning is in progress. 'doing_retune' only
covers re-tuning, not the initial tuning. Add another flag to detect the
initial tuning state and add a helper which tells us if any kind of
tuning is going on. Only implemented for MMC currently because that's
where we need it. SD can be added later if it becomes necessary.

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.
