The function imx_media_init_mbus_fmt() initializes the imx subdevice mbus colorimetry to some sane defaults when the subdevice is registered. Currently it guesses at a colorspace based on the passed mbus pixel format. If the format is RGB, it chooses colorspace V4L2_COLORSPACE_SRGB, and if the format is YUV, it chooses V4L2_COLORSPACE_SMPTE170M. While that might be a good guess, it's not necessarily true that a RGB pixel format encoding uses a SRGB colorspace, or that a YUV encoding uses a SMPTE170M colorspace. Instead of making this dubious guess, just default the colorspace to SRGB.

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.
