Thus calling regmap_init_spi in soc-io.c has below build error. ERROR: "regmap_init_spi" [sound/soc/snd-soc-core.ko] undefined! make[1]: *** [__modpost] Error 1 make: *** [modules] Error 2 This patch fixes the build error by adding CONFIG_REGMAP_I2C/CONFIG_REGMAP_SPI guards for regmap_init_i2c/regmap_init_spi.
