The imx_media_pixfmt structures include a codes member that stores media bus codes as a fixed array of 4 integers. The functions dealing with the imx_media_pixfmt structures assume that the array of codes is terminated by a 0 element. This mechanism is fragile, as demonstrated by several instances of the structure containing 4 non-zero codes. Fix this by turning the array into a pointer, and providing an IMX_BUS_FMTS macro to initialize the codes member with a guaranteed 0 element at the end. [Fixed a NULL deref of the codes pointer in a couple places] [Added more comments for the struct imx_media_pixfmt members, including a bold NOTE! for future developers that codes pointer is NULL for the in-memory-only formats] Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Steve Longerbeam <slongerbeam@gmail.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab+huawei@kernel.org>
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.
