From bbb758a6943e19c483ab752cf8220140b46cf22c Mon Sep 17 00:00:00 2001 From: Boris Faure Date: Thu, 29 Jan 2026 14:14:54 +0000 Subject: [PATCH] ASoC: sdca: Fix missing regmap dependencies in Kconfig 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.
