If one of the two is a loadable module, the combined driver must not be built-in:
aarch64-linux-ld: sound/soc/codecs/rt5682.o: in function `rt5682_sdw_hw_free': rt5682.c:(.text+0xb34): undefined reference to `sdw_stream_remove_slave' aarch64-linux-ld: sound/soc/codecs/rt5682.o: in function `rt5682_sdw_hw_params': rt5682.c:(.text+0xe78): undefined reference to `sdw_stream_add_slave' In particular, the soundwire driver must not be built-in if CONFIG_I2C=m.
