When CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH is enabled without
CONFIG_EXPERT, there is a Kconfig warning about unmet dependencies:
WARNING: unmet direct dependencies detected for SND_SOC_SDW_MOCKUP
Depends on [n]: SOUND [=y] && !UML && SND [=y] && SND_SOC [=y] &&
EXPERT [=n] && SOUNDWIRE [=y]
Selected by [y]:
- SND_SOC_INTEL_SOUNDWIRE_SOF_MACH [=y] && ...
Selecting a symbol does not account for dependencies. There are three
ways to resolve this:
1. Make CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH select
CONFIG_SND_SOC_SDW_MOCKUP only if CONFIG_EXPERT is set.
2. Make CONFIG_SND_SOC_SDW_MOCKUP's prompt depend on CONFIG_EXPERT so
that it can be selected by options that only depend on
CONFIG_SOUNDWIRE but still appear as a prompt to the user when
CONFIG_EXPERT is set.
3. Make CONFIG_SND_SOC_INTEL_SOUNDWIRE_SOF_MACH imply
CONFIG_SND_SOC_SDW_MOCKUP, which will select
CONFIG_SND_SOC_SDW_MOCKUP when its dependencies are enabled but still
allow the user to disable it.
Go with the third option as it gives the most flexibility while
retaining the original intent of the select.

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.
