With SND_SOC_RT5514_SPI=m and SND_SOC_RT5514=y, we get this link error:

sound/soc/codecs/rt5514.o: In function `rt5514_dsp_voice_wake_up_put': rt5514.c:(.text+0x2068): undefined reference to `rt5514_spi_burst_write' rt5514.c:(.text+0x20c8): undefined reference to `rt5514_spi_burst_write'

This adds another Kconfig symbol to work around the link error, forcing the main driver to be a loadable module as well if some other driver selects the I2C side to be built-in.

Fixes: 2a18483a7fb4 ("ASoC: Intel: Add Kabylake machine driver for RT5514, RT5663 and MAX98927") Signed-off-by: Arnd Bergmann arnd@arndb.de --- This can now lead to a configuration with SND_SOC_INTEL_KBL_RT5663_RT5514_MAX98927_MACH=y and SND_SOC_RT5514=m. I don't know if that is a problem or not.

An alternative approach would be to flip the dependency between rt5514_spi.ko and rt5514.ko and avoid having the rt5514_spi_burst_write symbol exported. --- sound/soc/codecs/Kconfig | 7 ++++++- sound/soc/intel/Kconfig | 2 +- sound/soc/mediatek/Kconfig | 2 +- sound/soc/rockchip/Kconfig | 1 - 4 files changed, 8 insertions(+), 4 deletions(-)
