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.
Fixes: 0ccac3bcf356 ("ASoC: Intel: boards: sof_sdw: add SoundWire mockup codecs for tests") Suggested-by: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com Signed-off-by: Nathan Chancellor nathan@kernel.org ---
v1 -> v2:
* Switch to imply rather than select ... if ... (Pierre-Louis).
* Reword commit message to explain different solutions rather than explain the problem in depth.
