The SDCA modules failed to build with modpost errors: ERROR: modpost: "__devm_regmap_init_sdw" [sound/soc/sdca/snd-soc-sdca-class.ko] undefined! ERROR: modpost: "__devm_regmap_init_sdw_mbq" [sound/soc/sdca/snd-soc-sdca-class-function.ko] undefined! The issue occurs because: - sdca_class.c calls devm_regmap_init_sdw() which requires REGMAP_SOUNDWIRE - sdca_class_function.c calls devm_regmap_init_sdw_mbq_cfg() which requires REGMAP_SOUNDWIRE_MBQ However, the Kconfig didn't select these dependencies, causing the symbols to be unavailable when the SDCA modules are built. Fix this by adding: - select REGMAP_SOUNDWIRE to SND_SOC_SDCA_CLASS - select REGMAP_SOUNDWIRE_MBQ to SND_SOC_SDCA_CLASS_FUNCTION This ensures the required regmap drivers are enabled when building SDCA support. Configuration after fix: CONFIG_SND_SOC_SDCA_CLASS=m CONFIG_SND_SOC_SDCA_CLASS_FUNCTION=m CONFIG_REGMAP_SOUNDWIRE=m CONFIG_REGMAP_SOUNDWIRE_MBQ=m Signed-off-by: Boris Faure <boris@fau.re> Link: https://patch.msgid.link/20260129141419.13843-1-boris@fau.re Signed-off-by: Mark Brown <broonie@kernel.org>
