Nikhil Devshatwar 8c324ef0b4 media: ti-vpe: cal: Restrict DMA to avoid memory corruption
[ Upstream commit 6e72eab2e7b7a157d554b8f9faed7676047be7c1 ]

When setting DMA for video capture from CSI channel, if the DMA size
is not given, it ends up writing as much data as sent by the camera.

This may lead to overwriting the buffers causing memory corruption.
Observed green lines on the default framebuffer.

Restrict the DMA to maximum height as specified in the S_FMT ioctl.

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.
