The i2c is dependency for the i2c codec drivers, so machine should depend on i2c. WIthout this we get build failures if I2C is not selected sound/soc/codecs/rl6347a.c: In function 'rl6347a_hw_write': >> sound/soc/codecs/rl6347a.c:66:8: error: implicit declaration of function >> 'i2c_master_send' [-Werror=implicit-function-declaration] ret = i2c_master_send(client, data, 4); ^ sound/soc/codecs/rl6347a.c: In function 'rl6347a_hw_read': >> sound/soc/codecs/rl6347a.c:114:8: error: implicit declaration of function >> 'i2c_transfer' [-Werror=implicit-function-declaration] ret = i2c_transfer(client->adapter, xfer, 2); Reported-by: kbuild test robot <fengguang.wu@xxxxxxxxx> Signed-off-by: Vinod Koul <vinod.koul@xxxxxxxxx> --- sound/soc/intel/Kconfig | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/sound/soc/intel/Kconfig b/sound/soc/intel/Kconfig index 13a762172b5d..2903823ebee1 100644 --- a/sound/soc/intel/Kconfig +++ b/sound/soc/intel/Kconfig @@ -145,7 +145,7 @@ config SND_SOC_INTEL_SKYLAKE config SND_SOC_INTEL_SKL_RT286_MACH tristate "ASoC Audio driver for SKL with RT286 I2S mode" - depends on X86 && ACPI + depends on X86 && ACPI && I2C select SND_SOC_INTEL_SST select SND_SOC_INTEL_SKYLAKE select SND_SOC_RT286 -- 1.9.1 _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
