At the moment, we have a decent amount of integration tests (selftests) covering different aspects of the sound subsystem. However, a lot of of sound-related in-kernel functions remains uncovered. This patch introduces the KUnit test for the core part of the sound subsystem. It includes 10 test cases: - Coverage of the format-related inline functions from 'pcm.h' header file: snd_pcm_format_physical_width, snd_pcm_format_width, snd_pcm_format_signed, test_format_endianness - Coverage of the available bytes counting functions from 'pcm.h' header: snd_pcm_capture_avail, snd_pcm_playback_avail - Coverage of functions from pcm_misc: snd_pcm_format_set_silence, snd_pcm_format_name - Coverage of card-related functions from init.c: snd_card_set_id, snd_component_add This patch depends on the previous patches in this patch series as they contain fix for the bug, which was found during the test development. Without them, the test doesn't pass.

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.
