Since the beginning the second clock ('special', 'sclk') was optional and
it is not available on some variants of Exynos SoCs (i.e. Exynos5420 with
v7 of MFC hardware).
However commit 1bce6fb3ed ("[media] s5p-mfc: Rework clock handling")
made handling of all specified clocks mandatory. This patch restores
original behavior of the driver and fixes its operation on
Exynos5420 SoCs.

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.
