ASoC: sdca: Fix missing regmap dependencies in Kconfig

Browse source

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
