ASoC: sdca: Fix missing regmap dependencies in Kconfig
commit bbb758a6943e19c483ab752cf8220140b46cf22c upstream.
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
