Nicolas Dufresne 132c88614f media: cedrus: Fix SUNXI tile size calculation 
Tiled formats requires full rows being allocated (even for Chroma
planes). When the number of Luma tiles is odd, we need to round up
to twice the tile width in order to roundup the number of Chroma
tiles.

This was notice with a crash running BA1_FT_C compliance test using
sunxi tiles using GStreamer. Cedrus driver would allocate 9 rows for
Luma, but only 4.5 rows for Chroma, causing userspace to crash.

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.
