The driver supports multiple hardware variants of Exynos I2C controller
which differ in FIFO depth, handling of interrupts and bus recovery in
HSI2C_MASTER_ST_LOSE state.
The difference in variant was a single bit set for Exynos7 variants and
implicit lack of this bit for other variants.
Make each variant explicit which also fixes the GCC warning about
documentation:
drivers/i2c/busses/i2c-exynos5.c:223: warning: Function parameter or member 'hw' not described in 'exynos_hsi2c_variant'
No change in functionality.

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.
