The FWHT stateless 'uAPI' was staging and marked explicitly in the V4L2 specification that it will change and is unstable. Note that these control IDs were never exported as a public API, they were only defined in kernel-local headers (fwht-ctrls.h). Now, the FWHT stateless controls is ready to be part of the stable uAPI. While not too late: - Rename V4L2_CID_MPEG_VIDEO_FWHT_PARAMS to V4L2_CID_STATELESS_FWHT_PARAMS. - Move the contents of fwht-ctrls.h to v4l2-controls.h. - Move the public parts of drivers/media/test-drivers/vicodec/codec-fwht.h to v4l2-controls.h. - Add V4L2_CTRL_TYPE_FWHT_PARAMS control initialization and validation. - Add p_fwht_params to struct v4l2_ext_control.

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.
